<h3>What is
Superficial peroneal nerve?</h3>
The greater portion of the dorsum of the foot, the fibularis longus, and the fibularis brevis muscles are all innervated by the superficial fibular nerve, which is also referred to as the superficial peroneal nerve (with the exception of the first web space, which is innervated by the deep fibular nerve). The major nerve in the lateral compartment of the leg is the superficial fibular nerve. The muscles of the fibularis longus and fibularis brevis are where it starts, on the side of the fibula neck. It falls between the fibularis longus and fibularis brevis in the middle part of the leg, then reaches the anterior border of the latter to enter the groove between the latter.

Answer:
The correct answer is A.
Explanation:
B-lympocytes participate in antibody-mediated immunity (also called humoral immunity)- They activate in the lymph nodes and/or in lymphatic organs when they are exposed to an antigen.
Also T-lymphocytes participate in cell-mediated immunity, they release different types of cytokines when they are exposed to an antigen. Macrophages and natural killer cells also participate in this type of immunity.
Alcohol and drugs can alter people's judgment. They may take risks that might expose them to HIV that they would not take when sober.
Sharing needles to inject drugs (such as heroin, speed, or anabolic steroids) is VERY dangerous and can easily spread HIV (and other serious diseases) from one person to another.
Some people who are addicted to drugs may trade sex for drugs or money to get more drugs. This may put them at greater risk of HIV, especially if they do not always practice safe sex.
