In the reaction
`underset(H^(+))overset(H_(2)O^(18))rarrA`, the product (A) has the structure:
A. `CH_(3)-underset(.^(18)OH)underset(|)overset(CH_(3))underset(|)C-CH_(2)OH`
B. `CH_(3)-underset(OH)underset(|)overset(CH_(3))overset(|)C-CH_(2).^(18)OH`
C. `CH_(3)-underset(.^(18)OH)underset(|)overset(CH_(3))overset(|)C-CH_(3)`
D. `CH_(3)-overset(CH_(3))overset(|)CH-CH_(2).^(18)OH`
