When a minor attains majority, there are certain legal implications that need to be considered. One such implication is whether the minor becomes a partner with unlimited liability in a partnership firm. The correct answer to this question is option 'D', which states that the minor is deemed to be a partner with unlimited liability from either the date he attains majority or the date it comes to his knowledge, whichever is later.

Explanation:

Definition of a minor: A minor is an individual who has not yet reached the age of majority, which is generally 18 years old. In some jurisdictions, the age of majority may vary.

Liability of a minor in a partnership firm: A minor is not personally liable for the debts and obligations of a partnership firm. This means that if the firm incurs any losses or liabilities, the minor's liability is limited to the extent of his capital contribution. The other partners, who are adults, are personally liable for the firm's debts.

Attainment of majority: When a minor reaches the age of majority, he becomes capable of entering into contracts and assuming full legal responsibility. This means that he can become a partner with unlimited liability in a partnership firm.

Date of becoming a partner with unlimited liability: According to the question, the minor is deemed to be a partner with unlimited liability from either the date he attains majority or the date it comes to his knowledge, whichever is later. This means that if the minor becomes aware of his status as a partner after attaining majority, he will be considered a partner with unlimited liability from that later date.

Reasoning behind the correct answer: The reason for this provision is to protect the interests of the minor. If the minor is not aware of his status as a partner, he may unknowingly assume unlimited liability for the firm's debts. By allowing the minor to become a partner with unlimited liability from the date of his knowledge, it ensures that he has the opportunity to make an informed decision about his participation in the partnership.

In conclusion, when a minor attains majority, he is deemed to be a partner with unlimited liability from either the date he attains majority or the date it comes to his knowledge, whichever is later. This provision ensures that the minor has the opportunity to make an informed decision about his liability in the partnership.
