Why did the Author call Agha Shahid Ali?

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.   The first time that Agha Shahid Ali spoke to me about his approaching death was on 25 April 2001. The conversation began routinely. I had telephoned to remind him that we had been invited to a friend’s house for lunch and that I was going to come by his apartment to pick him up. Although he had been under treatment for cancer for some fourteen months, Shahid was still on his feet and perfectly lucid, except for occasional lapses of memory. I heard him thumbing through his engagement book and then suddenly he said: ‘Oh dear. I can’t see a thing.’ There was a brief pause and then he added: ‘I hope this doesn’t mean that I’m dying...’Although Shahid and I had talked a great deal over the last many weeks, I had never before heard him touch on the subject of death. I did not know how to respond: his voice was completely at odds with the content of what he had just said, light to the point of jocularity. I mumbled something innocuous: ‘No Shahid. Of course not. You’ll be fine.’
