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.
A golden rule'is a rule which
- Abrings profit
- Bis very important
- Cis very difficult
- Dis very easy
Explanation
The passage calls the principle of present-giving — never give what you would not rather keep — 'the golden rule', saying it 'imperatively applies'. A 'golden rule' is a fundamental, highly important principle, not merely a profitable, difficult, or easy one. Its importance is underscored by the word 'imperatively'. Hence option (B) is correct.
