Question

Je vais cherches mon _ dans cette armoire.

Answer 1

First of all the question is wrong

if it is futur proche, then chercher would be in infinitive form so the correct question would be

Je vais chercher mon _______ dans cette armoire.

Of which the answer can be a clothing kept in the armoire(cupboard)

since mon is masculine we would be using a masculine cllothing like manteau which makes sense as when translated to english means I am going to search for my coat in this cupboard.

So the answer is

Je vais chercher mon manteau dans cette armoire.

hope it helps
