Consider the following sequence of reactions
`C_(2)H_(5)C -= CH overset(CH_(3)MgBr)rarr A underset((2)H_(2)O^(+))overset((1)HCHO) rarr B`
The product `(B)` is
A. `C_(2)H_(5)C -= C-overset(OH)overset(|)(CH)-CH_(3)`
B. `C_(2)H_(5)C-= C-CH_(2)OH`
C. `C_(2)H_(5)overset(CH_(3))overset(|)(C) = CHCH_(2)OH`
D. `CH_(3)CH_(2)OH`
