TOEIC grammar question

Upon entering, proceed to the sign-in table and present your __________________ form to one of the conference administrators.
(A) registering
(B) registration
(C) register
(D) to register

The answer is (B),But why not do (A)
In back of space,"form" as a objective should be modified by gerund.
I think (A) should be the best answer.
Who someone could tell me why (B) is the best answer?

B is the only adjective.
Some verbs can be changed to adjectives by additing 'ing' but not 'register'.

P.S. 'Registering' can also be an adjective but not in the context.

In this case "registration" is an attributive noun. It acts as an adjective that modifies "form". It becomes a form for registration. If you use "registering", it is a participle which could be an adjective. But it would leave us with a form that is registering. Forms don't register.

A similar example would be an 'application form' - not "applying form".
They are compound nouns, aren't they?

'Registering people have to submit the form by the deadline.'
Is it correct?

No, it goes with the people who are responsible for the registration i.e. registering authority, registering officer.

Registrant is also a word.

'People who wish to register have to ...' sounds more natural to me.
(The 'people' in your version looks/sounds like the object of the gerund 'registering'.)

This is a good question.

With doors alone, there are different types. There is revolving door, swing door (why not swinging door?), sliding door, roller shutter door, foldable door, collapsible door, etc.

I don't think that there is a definite rule/pattern as to the use of verb derivatives as adjectives.

Because the door is for entrance instead of revolution, IMO.

It's very unlikely that TOEIC, which stands for 'Test of English for International Communication', is set to test grammar skills. Indeed, many learners like doing grammar because it gives a certain sense of achievement but in exams grammar analyses can be very time-consuming. By contrast, a lot of time could be saved by simply ticking a familiar phrase. Such common collocations like 'registration/application form', 'board meeting', 'assistant director' and plenty of others can easily be picked up while excessive reading and listening, which some candidates surprisingly tend to ignore.

On a more 'linguistic' note, it's typical of English to use nouns to describe other nouns, e.g. 'school uniform', 'house work', 'programme manager'...

A form doesn't register, as MikeNewYork pointed out, but a door does revolves. We use a form to complete our registration but we don't [normally] use doors to complete/make a revolution, at least not for this purpose. It all seems not so much about grammar but about the meaning.

I agree. I would spell it as 'housework', though.

Yes, so would I. Not the best example probably but it usually helps to see the pattern.
