Which prefix means limb?

• A. Brachy-
• B. Brachi(o)
• C. Bio-

Answer: (B)

Brachi(o)- is the combining form that means arm or limb. It shows up in terms like brachial artery or brachial muscles, where the reference is to the arm. The other options represent different ideas: brachy- means short, bio- means life, and brady- means slow. So the prefix that denotes a limb is brachi(o)-.
