In the following carbocation, `H//CH_(3)` that is most likely to migrate to the positve charged carbon is :
`H_(3)overset(1)C-overset(H)overset(|2)underset(OH)underset("| ")"C"-underset(H)underset(3|)overset(+)C-overset(H)overset(|4)underset(""CH_(3))underset("| ")"C "-overset(5)CH_(3)`
A. `CH_(3)` at C-4
B. H at C-4
C. `CH_(3)` at C-2
D. H at C-2
