Hi!Welcome to the forum.
For multiple-choice questions, we like to have your opinion before we share ours. Thank you.
I got it! Thank you very much!"Composition" is an alternative word for "essay", and in BE it is - or was - the usual term for our attempts at creative writing in primary school. We don't often talk about "composing an essay" though it is possible and it's the best choice of the three.
Edit: I think it would mean "write with care", rather than just "write". I "composed" a letter of complaint means that I took a lot of care in the writing of it.
