Answer 1

Hint: Tetanus, also known as lockjaw is a bacterial infection caused by Clostridium tetani, which is commonly found in soil, saliva, dust, or manure.

Complete answer
The bacteria normally enter from the soil through a break in the skin through the cut. They produce toxins that interfere with normal muscle contractions and it causes muscle spasms. It's called lockjaw because the infection often causes the muscle to contract in the jaw and neck. Tetanus is an acute and serious infection of the central nervous system caused by bacterial infection of open wounds. In tetanus, spasms of the jaw and laryngeal muscles may occur during the late stages, Back muscle spasms often cause arcing called opisthotonos.The early sign is the locking of the jaw and the facial spasms called risus sardonicus. The second type of tetanus is traumatic tetanus, in England, it refers to " lockjaw ".In strychnine poisoning, trismus or lockjaw is generally secondary to spasm of the other muscles, whereas, in tetanus, it is generally the first symptom, no relaxation taking place between the spasms. Tetanus is a bacterial disease that affects the nervous system. Hence "Lockjaw" is another name of tetanus.

Hence the correct answer is option C.
