Question

one of my classmates...... gone to srinagar ​

Answer 1

Then what is the question.

Answer 2

ANSWER:

One of my classmates __has__ gone to Srinagar.

EXPLANATION:

     In the above sentence it is described that one of the narrator's friend has gone to Srinagar, here 'has' would describe properly where has the friend gone and without the presence of 'has' the sentence would not make much sense when put into perspective of the rest of the sentence.

   So, has is the word that can perfectly match the tense and the right usage of word at the same time.
