• B. Sun rising from west.
• C. Vehicle moving on the road meets an accident.
• D. none of the above.

Answer 1

The correct option is A Christmas will be on 25th December of this year.

Certain Event means that an event will surely happen. The probability of that event will be always 1.

The right answer is - Christmas will be on 25th December of this year. The probability of Christmas occurring on 25th December will be always 1.

Other events - Sun rises from the west (it will be an impossible event) and Vehicle meeting an accident is not sure to happen.
