The correct option to determine a Mersenne prime is:
2: \(2^n - 1\)
Mersenne primes are of the form \(M_n = 2^n - 1\), where \(n\) is a prime number.

Are you sure
Yes, I am sure. Mersenne primes are defined as primes of the form \(M_n = 2^n - 1\), where \(n\) is a prime number itself.
So, the expression that can be used to determine a Mersenne prime among your options is indeed:
2: \(2^n - 1\)
If \(n\) is prime, then \(2^n - 1\) may be prime, and this specific form is what defines Mersenne primes.
