C
$4-$ Bromo $-2-$ chloro $-5-$ iodo $-1-$ fluoro benzene
D
$2-$ Bromo $-3-$ chloro $- 1-$ iodo $-5-$ fluoro benzene

✓

Answer

Correct option: B.

$2-$ Bromo $-1-$ chloro $-5-$ fluoro $-3-$ iodo benzene

b
Numbering is according to lowest set of locant rule. Do numbering of substituent alphabetically.

$\therefore$ IUPAC name $=2$-bromo-$1$-chloro-$5$-fluoro-$3$-iodobenzene.
