@Thenuka-NaBH₄ can only be used to reduce ketones and aldehydes.

Something like this probably?

NaBH4 is a mild reducing agent. so it can not be used to reduce carboxylic acids and esters. but mind that that mistake will not blow up the whole question. they will give the part marks. other thing is you can not put a covalent bond between carbon atom and Mg in the grinard reagent.
