a. triangle
b. circle
c. rectangle
d. base

Explanation:

Step1: Analyze the components of a cylinder

A cylinder has two circular bases. When we unfold the lateral surface of a cylinder, we get a rectangle (if we consider the lateral - surface development).

Step2: Check each option

• Option b: A cylinder has two circular bases, so a circle is a component.
• Option c: The lateral surface of a cylinder (when un - rolled) is a rectangle.
• Option d: A cylinder has two bases (which are circles).
• Option a: A triangle is not a component of a cylinder.

Answer:

A. Triangle
