Solution

The correct option is B


Markovnikov's addition of HBr happens through the formation of Carbocation via Electrophilic addition of the given compounds, the most reactive would form the most (of given) stable carbocation.
Except option (c)

others are all symmetrical (both carbon atoms have equal no of hydrogen atoms)

Most substituted alkene is most stable (in general) so (d) is most stable with one less substitution, (c) is slightly less stable.

(a) Has its configuration with one less substitution then (c)

The intermediate formed for HBr addition (Markovnikov) in the case of (b) is resonance stabilized.

A is stabilized by resonance
