Answer:

A. 26

Read Explanation:

Observe the pattern:

7 3=7²+3²=49+9=58</p><pdatapxy="true"style="color:rgb(0,0,0);margintop:2px;marginbottom:2px;">6 3 = 7² + 3² = 49 + 9 = 58</p><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;">6 2 = 6² + 2² = 36 + 4 = 40

So,

5 $ 1 = 5² + 1²

5²+1²=25+1=26

Therefore, the answer is 26.
