To find out how many boys chose soccer or football as their favorite sport, we can refer to the data provided in the table.
- The number of boys who chose soccer: 54
- The number of boys who chose football: 71
Now, let's add these two numbers together:
\[ 54 \text{ (soccer)} + 71 \text{ (football)} = 125 \]
So, 125 boys chose soccer or football as their favorite sport.
Thus, the correct response is 125.
