Explanation

I am sorry about what happened yesterday. It Won't happen again.

کل جو ہوا اس پر مجھے افسوس ہے۔ یہ دوبارہ نہیں ہوگا۔

***

We use the simple future to talk about an action or condition that will begin and end in the future.

The formula for the simple future in the negative is will + not + [root form of verb], that is, will not, or, won't.

Hence, Option B is correct
