Options

A. `BH_(3)`

C. `(BH_(3))_(3)`

Answer

A

Explanation

`BH_(3)` is the electrophile. It leads to the `C` with greater number of hydrogens. Thus, it is a Markvniko-type addition. `BH_(3)` by itself does not exist. Its dimer `B_(2)H_(6)` is dissolved in a coodinate convalent bond with the `O` of the ether.
