💡 Detailed Explanation
The speaker is politely declining an offer using the set phrase '見送らせてください' (let me pass on this). The correct response is to accept this refusal gracefully, such as 'I see. Well, perhaps another time.' ('そうですか。またの機会にお願いします。'). Option 1 misunderstands the refusal as acceptance. Option 3 is a phrase used by someone *declining* a gift or offer, so it would be strange for the person *making* the offer to say it in response.
