Which of the following is a type of synovial joint?

Pivot
Fused
Serous
Elastic

The correct answer is: Pivot

A pivot joint is indeed a type of synovial joint, which allows for rotational movement around a single axis. This type of joint is exemplified by the joint between the first and second cervical vertebrae (the atlas and axis), which permits the head to turn from side to side. The defining characteristic of synovial joints is that they have a synovial cavity filled with fluid that helps to lubricate the joint, allowing for smooth movement. The other options listed do not fit the criteria for synovial joints. A fused joint typically refers to a situation where two bones grow together, eliminating movement; such joints are classified as fibrous joints. Serous refers to a type of tissue fluid and not a joint type, while elastic pertains to the flexibility of tissues and does not represent a classification of joints. Thus, the choice of a pivot joint aligns correctly with the definition and characteristics of synovial joints.
