Final answer:
The correct logical conjunction is 'Drew liked roses, and Drew loves lilies,' as it combines the two sentences into one without implying contrast.
Step-by-step explanation:
The correct logical conjunction to combine the two phrases 'Drew liked roses.' and 'Drew loves lilies.' is 'Drew liked roses, and Drew loves lilies.' This creates a single sentence that conveys both of Drew's preferences using the conjunctive word 'and' to connect them. Option D ('Drew liked roses, but Drew loves lilies.') also correctly joins the phrases but implies a contrast between the two preferences rather than just combining them.
It's worth noting that in English grammar, the conjunction 'and' is used to connect words or groups of words of equal importance, while 'but' is used to show a contrast. Since both phrases are about Drew's likes, it is more appropriate to use 'and' for a compound sentence.
