Correct option is D
The given statement is: "One must work hard to be successful in life."
From this statement, the logical conclusion is that hard work is necessary for success. Let’s evaluate each option:
(a) A hardworking person is satisfied in life.
· This does not logically follow from the statement, as it mentions satisfaction, which is unrelated to the necessity of hard work for success.
(b) Life is related with hard work.
· This option is too vague and does not directly address the necessity of hard work for success.
(c) Only those who work hard will be able to pass.
· This is specific to passing and does not relate to the broader idea of success in life.
(d) Without hard work one cannot be successful in life.
· This option aligns perfectly with the statement, as it reinforces that hard work is essential for success.
Answer: (d) Without hard work one cannot be successful in life.
