Twin primes are pairs of primes that are two units apart (e.g., 11 and 13, 17 and 19). Among the options given, none are pairs of prime numbers. 89 is a prime number, but 91 is divisible by 7 and 13. 83 is prime, but 85 is divisible by 5. 91 and 93 are not prime; 91 is divisible by 7 and 13, and 93 is divisible by 3. Therefore, there are no twin primes between 80 and 100.
