Repotted speech টি সর্বজনীন সত্য হলো, indirect - এ রুপান্তর সময় Subject এবং Verb এর speech এর মাঝে শুধু That বসিয়ে indirect form করতে হবে। সুতরাং প্রদত্ত বাক্যটির indirect form হলো He said that we could not be quite happy in this life.

The correct indirect form of the sentence "He said, 'We cannot be quite happy in this life'" is:

"He said that we could not be quite happy in this life."

Explanation:

• Direct Speech: He said, "We cannot be quite happy in this life."
• Indirect Speech: When converting to indirect speech, pronouns and verb tenses need to be adjusted accordingly.

"He said that we could not be quite happy in this life."

• The pronoun "we" remains unchanged in the indirect speech because the speaker is referring to the same group.
• The verb tense changes from "cannot" to "could not" to maintain consistency with past reporting.

"He said that they cannot be quite happy in this life."

• The pronoun "they" is incorrect as it changes the reference from "we."

"He said that they could not be quite happy in this life."

• The pronoun "they" changes the reference from "we," making it incorrect.

"He said that we could not be quite happy in this life."

• This option is similar to the correct choice but lacks the word "that," which is needed for proper indirect speech structure.

Thus, the best and most accurate choice is: "He said that we could not be quite happy in this life."
