  3. Only conclusion II follows
  4. Either conclusion I or II follows.

Correct answer and explanation

Correct answer: Only conclusion II follows

Explanation: āœ… Correct Answer: C) Only conclusion II follows šŸ“š Explanation: Step 1: Map the statements using Venn diagrams. 'Some roads are metros' shows an overlap between the road and metro circles. 'Some metros are cars' establishes an overlap between metros and cars. Step 2: Analyze conclusion I. There is no certain information linking cars to roads, so saying all cars belong to either category cannot be verified. Step 3: Analyze conclusion II. Since it is explicitly stated that some metros are cars, it logically follows that some cars are metros. Therefore, only conclusion II is valid.
