Geographic (Geo) Match Conditions in AWS WAF. This new condition type allows you to use AWS WAF to restrict application access based on the geographic location of your viewers. With geo match conditions you can choose the countries from which AWS WAF should allow access. https://aws.amazon.com/about-aws/whats-new/2017/10/aws-waf-now-supports-geographic-match/

To meet the requirement of allowing the web application to be accessed from one specific country only, the company should configure AWS WAF (Web Application Firewall) on the Application Load Balancer in a VPC (Option C).
AWS WAF is a web application firewall service that helps protect web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. AWS WAF allows you to create rules that block or allow traffic based on the values of specific request parameters, such as IP address, HTTP header, or query string value. By configuring AWS WAF on the Application Load Balancer and creating rules that allow traffic from a specific country, the company can ensure that the web application is only accessible from that country.
