All scientists hold Ph.D. Some engineers are scientists. No scientist works without access to the laboratory. Which of the following are the most appropriate conclusions?
I. All scientists work in the laboratory.
II. Some engineers have Ph.D.
III. All engineers are scientists.
Select the most appropriate option:

• A. I and II follow
• B. I and III follow
• C. Only I follows
• D. All follow

Hint:

In syllogism questions, carefully apply the given statements; do not assume information not provided.

Answer 1

The Correct Option is A

Step 1: Analyze statements — All scientists hold Ph.D., no scientist works without a lab → I follows.
Step 2: Some engineers are scientists; since all scientists have Ph.D., some engineers have Ph.D. → II follows.
Step 3: All engineers are scientists → Not necessarily true. III does not follow.
Step 4: Conclusion — Only I and II follow.
