Which of the following compounds give a yellow precipitate with iodine and aqueous NaOH solution ?

Iodoform reaction is given by those compounds that have such groups:

$\mathrm{R}-\mathrm{CO}-{\mathrm{CH}}_3 \mathrm{and} \mathrm{R}-\mathrm{CH}\left(\mathrm{OH}\right)-{\mathrm{CH}}_3$

Acetophenone has (-CO-CH₃) group which means it gives iodoform.
