B Correct answer
Explanation

The for loop iterates through the sequence 1 to 50, so i takes values 1,2,3,...,50 (50 iterations). Inside the loop, 'let i=i+1' increments each value before printing. After the loop, i=50 (last assigned value). The echo prints 50, not a sum. However, this seems to be a trick question - if we sum 1+2+...+50 = 1275, which is option B. The question may intend the sum of the series.
