options:
2 + 1 + 3 = 6
2 + 2 + 2 = 6
1 + 1 + 1 + 1 + 1 + 1 = 6

Explanation:

Step1: Analyze the array structure

The array has 2 rows, each with 3 squares.

Step2: Identify repeated addition

We can add the number of squares in each row repeatedly: $3 + 3 = 6$, or add the number of squares in each column repeatedly: $2 + 2 + 2 = 6$.

Step3: Match to options

The option $2+2+2=6$ matches the column-based repeated addition.

Answer:

2+2+2=6
