Answer :
Let's break down this problem step-by-step:
1. We start by initializing `START` to 1 and `END` to 4.
2. We define a function `start` which initializes the variable `sum1` to 0.
3. We then use a `for` loop that starts at `i = START` and runs while `i <= END`, meaning the loop will run from `i = 1` to `i = 4`.
Here’s a breakdown of each iteration of the loop and the value of `sum1`:
- First Iteration:
- `i = 1`
- `sum1 = 0 + 1 = 1`
- Second Iteration:
- `i = 2`
- `sum1 = 1 + 2 = 3`
- Third Iteration:
- `i = 3`
- `sum1 = 3 + 3 = 6`
- Fourth Iteration:
- `i = 4`
- `sum1 = 6 + 4 = 10`
After the final iteration, the value of `sum1` is 10. Thus, the correct answer is:
D. 10
