Relative to the program translated by a compiler, the same program when interpreted runs
(A) Faster
(B) Slower
(C) At the same speed
(D) May be faster or slower
Answer: (B)

Compiler scans the entire program and translates it as a whole into machine code. It takes large amount of time to analyze the source code but the overall execution time is comparatively faster.
So, option (B) is correct.
