Statement - A man must be wise to be a good wrangler. Good wranglers are talkative and boring.
Conclusions - I. All the wise persons are boring.
II. All the wise persons are good wranglers.

Correct option is C

Let's analyze the given statement and the conclusions:
Statement:
- A man must be wise to be a good wrangler.
- Good wranglers are talkative and boring.
Conclusions:
I. All the wise persons are boring.
This conclusion is not necessarily true because the statement only mentions that good wranglers are talkative and boring. It does not say that all wise people are boring; only that if a person is a good wrangler, they are boring. Therefore, this conclusion does not logically follow from the statement.
II. All the wise persons are good wranglers.
This conclusion is also not true. The statement says that to be a good wrangler, a man must be wise. However, it does not imply that all wise persons are good wranglers. Therefore, this conclusion does not follow either.
Answer:
(c) Neither I nor II follow.
