The correct structure for `3,3`-bis (`1,1`-dimethylethyl)-`2,2,4,4`-tetramethylpentane is
A. (1) `CH_(3)underset(C_(2)H_(5))underset(|)(CH)-underset(C(CH_(3))_(3))underset(|)overset(C(CH_(3))_(3))overset(|)(C)-overset(C_(2)H_(5))overset(|)(CHCH_(3))`
B. (2) `(CH_(3))_(2)overset(C_(2)H_(5))overset(|)(C)-underset(CH(CH_(3))_(2))underset(|)overset(CH(CH_(3))_(2))overset(|)(C)-overset(C_(2)H_(5))overset(|)(CH(CH_(3))_(2))`
C. (3) `(CH_(3))_(3)C-underset(C(CH_(3))_(3))underset(|)overset(C(CH_(3))_(3))overset(|)(C)-C(CH_(3))_(3)`
D. (4) `CH_(3)CH_(2)CH_(2)CH-underset(C(CH_(3))_(3))underset(|)overset(C(CH_(3))_(3))overset(|)(C)-CHCH_(2)CH_(2)CH_(3)`
