C Correct answer
Explanation

Sequence is fundamental - every program executes statements sequentially (one after another) by default. Even the simplest program must execute statements in order. Selection (if/else) and repetition (loops) are optional control structures that programs may or may not use. "Switching" is not a standard control structure category.
