Who makes up the government ?
A. MPs
B. MLAs
C. President
D. Prime Minister
E. Ruling Parties

Dear Student,
MPs form the government at the Centre level. 
MLAs form the government at the State level.  
​​​​​​However, since your question talks about only 1 option, we can say that Ruling Parties form the government in general.
Option E. is the answer.
Regards,
