Who is the first Indian cricketer to score a triple century against Pakistan in a test innings?

Correct option is D

The correct answer is (d) Virender Sehwag. 
Explanation:
· Virender Sehwag was the first Indian cricketer to score a triple century in Test cricket, and he achieved this milestone against Pakistan.
· The innings of 309 runs came during the first Test match between India and Pakistan in Multan in March 2004.
· This historic knock earned him the nickname "Multan ka Sultan" (Sultan of Multan).
· Sehwag famously reached his triple century by hitting a six off the bowling of Saqlain Mushtaq. 
Information Booster:
· Virender Sehwag is one of only four batsmen in Test cricket history to have scored two triple centuries, with his second triple-hundred (319) coming against South Africa in 2008.
· The Multan innings of 309 was, at the time, the highest individual score by an Indian in Test cricket.
· India went on to win the Test match by an innings and 52 runs, largely thanks to Sehwag's dominant performance.
· The match was also notable for a controversial decision by then-captain Rahul Dravid to declare the innings with Sachin Tendulkar on 194 not out. 
Additional Knowledge: (a) Sachin Tendulkar
· A cricketing legend and the highest run-scorer in Test and ODI cricket, Sachin Tendulkar did not score a triple century against Pakistan. His highest Test score against Pakistan was 194 not out in the same Multan Test where Sehwag scored his 309. 
(b) Saurav Ganguli
· A former Indian captain and prolific middle-order batsman, Saurav Ganguly has never scored a triple century in Test cricket. His highest Test score was 239 against Pakistan in 2007. 
(c) Sunil Gavaskar
· A former Indian opener and batting great, Sunil Gavaskar was the first batsman to reach 10,000 runs in Test cricket, but he did not score a triple century against Pakistan or in his Test career. His highest Test score was 236 not out against the West Indies.
