答えを見る
正解: C) regardless
'Regardless of' is a compound preposition meaning 'irrespective of', and it takes the noun phrase 'their department' after it, so 'regardless' is correct. 'Regard' is a verb/noun, 'regarding' is a preposition meaning 'concerning' (a different meaning), and 'regarded' is a past participle. It's best memorized together with 'of'.
