✓
$C{H_3} - C{H_2} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits_| {\mkern 1mu} - C{H_2}}\limits^{C{H_3}\,\,\,\,\,\,\;\;\;\;} }\limits_{OH\,\,\,\,\,\;\;\;\;\;\;} {\mkern 1mu} - C{H_3}$
B
$C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,H}}\,-C{{H}_{3}}$
C
$C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-OH$
D
$C{H_3} - C{H_2} - \mathop {\mathop C\limits_| {\mkern 1mu} H - }\limits_{C{H_3}\,\,\,\,\;} {\mkern 1mu} C{H_2} - C{H_2} - OH$

✓

Answer

Correct option: A.

$C{H_3} - C{H_2} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits_| {\mkern 1mu} - C{H_2}}\limits^{C{H_3}\,\,\,\,\,\,\;\;\;\;} }\limits_{OH\,\,\,\,\,\;\;\;\;\;\;} {\mkern 1mu} - C{H_3}$

a
$C{H_3} - C{H_2} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits_| {\mkern 1mu} - C{H_2}}\limits^{C{H_3}\,\,\,\,\,\,\;\;\;\;} }\limits_{OH\,\,\,\,\,\;\;\;\;\;\;} {\mkern 1mu} - C{H_3}$ $\xrightarrow{{{H^ + }}}$ $C{H_3} - C{H_2} - \mathop {\mathop {{\text{ }}C}\limits_ \oplus ^| - C{H_2}}\limits^{C{H_{3\,\,\,\,\,\,}}\;\;\;\;{\kern 1pt} } - C{H_3}$

The more stable carbocation is generated thus more easily it will be dehydrated.
