正解: A) feel
This follows 'please' as part of an imperative sentence, so the verb must be the base form 'feel'. 'Feel free to do' is a set expression meaning 'please do not hesitate to'. 'Feels' is third-person singular, 'feeling' is a participle, and 'felt' is past tense — none can be used in an imperative sentence. Note that 'Should you have...' at the start is an inverted form of 'if you should have...', expressing a condition.
