A
B
C
D

Explanation


We know that in case of an unsymmetrical alkene there is the possibility of forming two products. In such cases the formation of major product is decided on the basis of Markownikoffs rule which is rationalized in terms of stability of the carbocation. Also 3o carbocation is more stable than 2o carbocation and 2o carbocation is more stable than 1o carbocation.
