Karnaugh Maps — Effect of Looping on Variables When grouping adjacent 1-cells on a K-map (looping), which variables are eliminated from the resulting simplified product term?

Difficulty: Easy

variables within the loop that appear only in their complemented form.
variables that remain unchanged within the loop.
variables within the loop that appear in both complemented and uncomplemented form.
variables within the loop that appear only in their uncomplemented form.

Correct Answer: variables within the loop that appear in both complemented and uncomplemented form.
