Who among the following won the Pakistan's Parliamentary Elections in July 2018 and became the Prime Minister?

1. A

   Nawaz Sharif

   (a) Nawaz Sharif. The three-time Prime Minister was disqualified in 2017 and was not the July 2018 winner. His party contested, but he is not the key.

2. B

   Imran Khan

   (b) Imran Khan. Pakistan Tehreek-e-Insaf won the 25 July 2018 general election; Imran Khan was elected Prime Minister in August. That stored name is the official key. The National Assembly majority was assembled with allies.

3. C

   Bilawal Bhutto

   (c) Bilawal Bhutto. He led the Pakistan Peoples Party in opposition, not into the premiership. It is not the key.

4. D

   Reham Khan

   (d) Reham Khan. She is a journalist and former spouse, not a parliamentary winner or Prime Minister.

Summary. Official key is (b) Imran Khan. The July 2018 Pakistan election made him Prime Minister for PTI. Nawaz Sharif was already disqualified; Bilawal Bhutto remained in opposition; Reham Khan was not a candidate for that office. Neighbouring facts are 25 July polling and Arif Alvi as President later in 2018.
