73 is the largest prime numbers I know about prime numbers like twin prime numbers and co- prime numbers

Introduction:
In order to determine the largest prime number among the given options, we need to understand the concept of prime numbers and how they can be identified. A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself. Let's analyze each option to identify the largest prime number.

Analysis:
1. Option A: 67
2. Option B: 96
3. Option C: 73

Option A: 67
67 is a prime number because it is only divisible by 1 and 67. There are no other positive integers that divide evenly into 67.

Option B: 96
96 is not a prime number because it has divisors other than 1 and itself. It can be divided evenly by 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.

Option C: 73
73 is a prime number because it is only divisible by 1 and 73. There are no other positive integers that divide evenly into 73.

Conclusion:
Out of the given options, the largest prime number is 73 (Option C). Both 67 (Option A) and 73 (Option C) are prime numbers, but 73 is greater than 67. Option B, 96, is not a prime number because it has divisors other than 1 and itself.
