Below is a statement followed by two assumptions. Determine which of the given assumption(s) is/are implicit in the statement.
Statement: Travelling from Indore to Delhi by train is convenient.
Assumptions: I. Travelling from Indore to Delhi by air is not convenient. II. Indore and Delhi are connected by train.
Options:

Correct option is B

Given: Statement praises the convenience of travelling from Indore to Delhi by train. Assumptions provided refer to air travel inconvenience and train connectivity.

Concept: Implicit logical deduction.

Solution:
Assumption I is invalid because positively stating that a train is convenient does not logically imply anything negative or comparative about air travel. Assumptions must strictly derive from the text.
Assumption II is valid and implicit. In order to evaluate or experience the convenience of a train journey between Indore and Delhi, it is a mandatory physical prerequisite that the two cities are actually connected by a train route.
Therefore, only Assumption II logically follows.

Final Answer: Only Assumption II is implicit.

So the correct answer is (b)
