Correct answer is B.
Because slow speed r. p.m. = 80 to 120,
Medium speed r.p.m. = 250 to 800,
High speed r.p.m. = above 900.
Because slow speed r. p.m. = 80 to 120,
Medium speed r.p.m. = 250 to 800,
High speed r.p.m. = above 900.

SLOW SPEED ENGINES - Engines which have rpm less than 300 r.p.m
MEDIUM SPEED ENGINES - Engines which have rpm ranging from 300-1000 r.p.m.
HIGH SPEED ENGINES - Engines which have rpm more than 1000 r.p.m.
Answer given is wrong.
