Answer:
d. is elected separately from the governor but succeeds the governor should the office be vacated.
Step-by-step explanation:
The Lieutenant Governor is the second most powerful person after the governor in Texas. He presides over the Senate. The present Lieutenant governor in Texas is Dan Patrick who has been on seat since January 20, 2015. The lieutenant governor is elected separately from the governor, which means that they could come from different political parties. In the absence of the governor, the lieutenant governor, succeeds him.
The lieutenant governor must have been a member of many legislative bodies. If the lieutenant governor should vacate his seat in the senate for whatever reason, the senate conducts an election among its members to chose a president pending the next state elections.
