Stuck on a Housewarming Gift? Crossword Clue Solved!

As a detective, I approached the crossword clue with the mindset of a detective. The use of the word ‘option’ caught my attention. I looked for a word that could be chosen as an option. My next clue was the question mark that indicated the answer was likely to be a play on words. My mind immediately went to items that people usually bring as gifts to house-warming parties. ‘Heat’ caught my attention. OILHEAT might be the perfect word play for this clue. The use of ‘oil’ in the answer hinted towards a word-play on ‘olive oil.’ However, the more common and fitting answer was OILHEAT.
