C. "NumericLessThan": {"aws:MultiFactorAuthAge": "7200"} This condition ensures that the action is allowed only if the MFA session age is less than 7200 seconds (2 hours), meaning it enforces the requirement that each MFA session remains valid for only 2 hours. This is a correct choice as it directly addresses the session validity requirement. D. "NumericGreaterThan": {"aws:MultiFactorAuthAge": "7200"} This condition would allow the action only if the MFA session age is greater than 7200 seconds, which is contrary to the requirement. Therefore, this option is incorrect.
