Passage:
Passage-II It is possible to give wedding presents, birthday and Christmas presents, without any thought of affection at all, they can be ordered by postcard; but the unbirthday present demands the nicest care. It is therefore the best of all, and it is the only kind to which the golden rule o f present-giving imperatively applies - the golden rule which insists that you must never give to another person anything that you would not rather keep: nothing that does not cost you a pang to part from. It would be better if this rule governed the choice also of those other three varieties of gifts, but they can be less exacting.
The 'unbirthday' present is the best o f all because
- Ait cannot be ordered by postcard
- Bit means giving expensive presents
- Cits choice needs the utmost care
- Dother occasions are better than birthdays for giving presents
Explanation
The author says the unbirthday present 'demands the nicest care' and is therefore 'the best of all'. Its superiority lies in the thought and care behind the choice, governed by the golden rule of giving only what it would pain you to part with. It is not about expense or about other occasions being better than birthdays. Hence option (C) is correct.
