which of the following are connected by a ball - and - socket joint?
a humerus and scapula
b radius to ulna
c radius to humerus
d ulna to humerus

Explanation:

A ball - and - socket joint allows for a wide range of motion. The humerus (upper arm bone) and scapula (shoulder blade) form the shoulder joint, which is a ball - and - socket joint. The radius and ulna are connected by a pivot joint. The radius and humerus, as well as the ulna and humerus, form hinge - like joints (elbow joint has both hinge - like and pivot - like components but not ball - and - socket).

Answer:

A. humerus and scapula
