C Correct answer
Explanation

Tetanus is also called lockjaw because the bacteria Clostridium tetani releases a toxin that causes severe muscle spasms, particularly in the jaw muscles (masseter muscles), making it difficult or impossible to open the mouth. This condition can be prevented through vaccination and is often associated with contaminated wounds.
