Greetings candidate,

According to NTA guidelines and rules, both the answers will be evaluated as correct answers. Since 2018, when JEE Mains went online, both the answers have been considered correct. So you don't have to worry about it. You will get full marks for that question if the provided answer is correct. Good luck.

Your answer might be evaluated as correct. Because the answer given by you i.e 4 is a correct answer only but not the accurate one. 4.00 is an accurate answer. Many of the competitive exams consider the accurate answer as the correct one.

Hope this information helps you.
