Myo- denotes muscle tissue. This combining form comes from Greek roots meaning muscle and is used in terms like myopathy (a muscle disease), myalgia (muscle pain), and myocyte (a muscle cell). That’s why the correct interpretation is that myo refers to muscle. The other options point to different structures (tail, shoulder, rib) and would use other roots such as caudal for tail, delto- or scapulo- for shoulder, and costo- or costal for rib. So, myo clearly signals muscle.
