I. 
II. 
III. 
IV.

Quizplus · Accepted Answer

Only molecules containing double bonds undergo addition type reactions with Br₂. Therefore, options I and IV cannot undergo substitution reactions with Br₂. Option III contains a tertiary carbon which is resistant to substitution reactions. Option II contains a primary carbon, and hence can undergo a substitution reaction with Br₂. Therefore, the best choice is B - II and III.
