@Aman Juyal in 2014, in IIT Roorkee question that you mentioned, if you consider that c pgm runs on TM, no options will match. So, there if you consider as finite machine, we will get one option and that was declared as answer.
Now in 2019 question, if you consider as finite machine, no options will match. But if you consider as TM, you will get "program will not terminate and will not print"
@Aman Juyal..Ya ok bro..I didn't comment to prove you wrong or anything like that. Since you referred 2014 question, I checked and answered. In my point of view, we can say that question is wrong or ambiguous only if different scenarios matches different answers. But in both 2014 and 2019, only one scenario(here either finite or infinite machine) gives the correct answer.
Let's see what's the answer present in the key
