This question is about a lifetime achievement award given to a Bollywood screenwriter in 2019. Javed Akhtar, Vishal Bhardwaj and Anurag Kashyap are all respected names in Hindi cinema writing, but none of them was the recipient that year, so all three can be grouped and set aside.
The honour went to Salim Khan, the writer behind iconic scripts such as Sholay, Deewaar and Zanjeer, recognising his long career shaping some of Hindi cinema's most memorable stories.
So the correct answer is Salim Khan.
Each name in this question belongs to a different generation of Hindi film writing, and tracing when each built their reputation helps identify who this particular lifetime award was meant for.
Looking at when each writer's major work took place points clearly to the veteran from the earliest generation among the four.
Therefore, the correct answer is Salim Khan.
