Option C is correct.

Step-by-step explanation:

A sequence is an arithmetic sequence when the difference between one term and the next term is the same. The first 10 counting numbers have a difference equal to 1. Skip counting by 5 has a difference equal to 5. Odd numbers have a difference equal to 2. But the prime numbers do not have the same difference. Thus, option c is not an arithmetic sequence.
