A developer is working on a feature branch and runs 'git merge main'. The command fails with: 'CONFLICT (content): Merge conflict in src/app.py'. The developer opens the file and sees conflict markers. What is the correct first step to resolve the conflict?

Edit the file to manually combine the changes from both branches, removing the conflict markers.

Run 'git reset --hard HEAD' to abort the merge and start over.

Run 'git checkout --ours' to automatically accept the current branch's version.

Run 'git merge --abort' to cancel the merge and return to the pre-merge state.

A JavaScript function divides two numbers: `function divide(a, b) { return a / b; }`. When called with `b = 0`, it returns `Infinity` instead of throwing an error. Which modification would make the function handle division by zero gracefully?

Add a check: `if (b === 0) { return 'Error: Division by zero'; }`

Wrap the division in a `try`/`catch` block.

Change the function to use the `%` operator instead of `/`.

Use `parseInt(b)` to convert `b` to an integer.
