A Correct answer
Explanation

Computer Science max marks = 40. A raw score of at least 30 means at least 30/40 = 75%. Looking at the Computer Science column: Ayush (80%), Aman (70%), Sajal (70%), Rohit (60%), Muskan (90%), Tanvi (60%), Tarun (80%). Students with >= 75% are Ayush, Muskan, and Tarun. Total = 3.

AI explanation

The maximum marks for Computer Science are 40, and securing a raw score of at least 30 requires obtaining 75% or more in the subject. The table shows the percentage of marks obtained by each student, so we must count those with 75 or higher. Ayush scored 80, Aman scored 70, Sajal scored 70, Rohit scored 60, Muskan scored 90, Tanvi scored 60, and Tarun scored 80. Only Ayush, Muskan, and Tarun achieved a score of 75 or higher, meaning 3 students met the condition.
