Step 1: Understand the statement (S).
The statement says: Economic security makes people better and happier and has a good influence on their personality.
So, economic security (financial stability) leads to:
Step 2: Check Conclusion I.
C I: "People who earn enough money are happier."
This directly follows from the part of S which says "economic security makes people happier."
\(\Rightarrow\) Conclusion I follows.
Step 3: Check Conclusion II.
C II: "To have a good personality people should be economically sound."
Since the statement clearly mentions that economic security has a good influence on personality, it implies economic soundness helps in developing a good personality.
\(\Rightarrow\) Conclusion II also follows.
Step 4: Final Answer.
Both conclusions follow logically. \[ \Rightarrow \boxed{(c)\ \text{Both Conclusions I and II follow}} \]
Rewrite the statement in categorical form and apply standard syllogism rules instead of paraphrasing it.
Both conclusions are direct restatements of the two predicates in the universal statement, so both hold.
the correct answer is Both Conclusions I and II follow.
