Question

what ordinal number do you hear? 2nd 7th 6th

Explanation:

Since the problem is about identifying the ordinal number heard, and assuming the correct one among the options is 6th (as a common example, though the actual audio is needed, but based on the options and typical such questions, if the audio corresponds to sixth, then 6th is the answer).

Answer:

C. 6th (assuming the audio corresponds to "sixth", if the audio was for 2nd it would be A, for 7th it would be B; here we assume the correct one is 6th among the given options)
