Statement: "Join X-tuition classes for sure success. Excellent teaching by excellent teachers is our strength." - An advertisement.
Assumptions:
1. Sure success is desirable.
2. Students expect sure success when they join any tuition class.
3. Just having excellent teachers does not ensure success.
Answer: A
The advertisement seeks to attract the students by promising them sure success. So, both I and II are implicit. Assumption III does not follow from the statement and so is not implicit.
