How many IPsec rules are there in Microsoft Firewall configuration?

In Microsoft Firewall configuration, there are four IPsec rules, which include rules for inbound and outbound traffic and specific actions on connection requests.

A. 2 is incorrect; the rule set is more comprehensive than this.
B. 5 exceeds the total IPsec rules available within the standard configuration.
C. 3 is insufficient, as all necessary rules must be accounted for in configurations.
