Answer:
C - If you do exercises regularly, your health will significantly improve
Explanation:
This is a conditional sentence.
The English language has three forms of conditional:
The Zero conditional is used to talk about things that are generally true such as: "If you heat ice, it melts"
The structure is if {simple present}, {simple present}
The First conditional is used to talk about future situations we believe are real or possible such as: "If I finish my chores, I'll play some games"
The structure is if {simple present}, {will + infinitive}
The second conditional is used to imagine situations that are unreal or unlikely, such as: "If I were a millionaire, I'd be happy"
The structure is if {simple past}, {would + infinitive}
The sentence given fits the First conditional better.
