In which year, the number of students have doubled with reference to the previous year in a particular program?
A2022
B2023 ✓ Correct
C2024
D2025
Correct answer: (B) 2023
Explanation
Scan each program for a year whose figure is exactly twice the previous year. In B.A. the count goes 225 in 2022 to 450 in 2023, and 225 multiplied by 2 is 450, an exact doubling. No other program doubles across consecutive years, so the year is 2023.
