Identify the one which shows E-Z mechanism?

Identify the one which shows E-Z mechanism? Correct Answer 3-methylpent-2-ene

In ‘z’ mechanism, the compounds with higher priority will be located opposite to each other of the double bond, in ‘E’ mechanism the compounds with high priority will be located in z corners and hence 3-methylpent-2-ene is the one which shows E-Z mechanism in which the priority group is CH3 and CH2CH3.
