Concept:Correct spelling of words like "strolled" and "lackadaisically" is the focus here. "Strolled" means walked slowly, and "lackadaisically" means in a lazy, relaxed manner.Explanation:Option A uses "strolled" (double 'l' and one 'r') and "lackadaisically" (correctly spelled with 'dai' after 'ka'). This matches standard spelling. Option B has "stroled" (missing one 'l') and "lackadaissically" (extra 's'). Option C spells "lackadiassically" incorrectly (wrong 'i' and double 's'). Option D has "strrolled" (extra 'r') and "lackadaisicaly" (missing 'l' before 'y').Only Option A contains both words spelled correctly as per English dictionaries. The other options contain spelling errors that change the meaning or make them incorrect.Answer:Option A: He strolled lackadaisically through the park, seemingly without a care, enjoying the gentle breeze and the warmth of the sun.
