Shown on the left is a set of equations. Which option belongs to the same set?
A
B
C
D
Step 1: Analyze the relationship between each symbol. Note that all equations follow a pattern, where certain operations involving symbols result in a specific value.
Step 2: Using the first equation, we observe that \( \triangle \times \) leads to \( \square \). Next, apply the operations to each option and identify the one that maintains consistency with the pattern in the original set of equations.
Step 3: Option (C) correctly follows the pattern from the original equations.
