Explanation:

The 2023 FIH Men's Hockey World Cup was hosted by **India**. This marked the fourth time India hosted the prestigious tournament, with matches held in Bhubaneswar and Rourkela, Odisha. Option (A) England has a strong hockey tradition and has hosted major tournaments, but not the 2023 Men's World Cup. Option (B) Germany is a powerhouse in international hockey and has also hosted World Cups, but was not the host in 2023; they were the eventual champions. Option (C) Belgium, another top hockey nation, was the defending champion in 2023 but did not host the tournament. Therefore, India was the designated host country for the 2023 FIH Men's Hockey World Cup.
