Which of the following is correct order with respect to acidic nature :

$C H \equiv C H > C H_{3} - C \equiv C H > C H_{2} = C H_{2} > C H_{3} - C H_{3}$
$C H \equiv C H > C H_{2} = C H_{2} > C H_{3} - C \equiv C H > C H_{3} - C H_{3}$
$C H_{2} = C H_{2} > C H_{3} - C H_{3} > C H \equiv C H > C H_{3} - C \equiv C H$
$C H_{3} - C H_{3} > C H_{3} - C \equiv C H > C H_{2} = C H_{2} > C H \equiv C H$
