Final answer:
In Spanish, 'más' means 'more' when used alone, but 'most' when used after 'el', 'la', 'los', or 'las'. 'Menos' can mean 'less' or 'least'. So, the correct option is A) less, least.
Step-by-step explanation:
In Spanish, when the adverb más is used alone, it means 'more'. However, when it is used after el, la, los, or las, it means 'most'.
For example, 'el más alto' means 'the tallest' and 'la más inteligente' means 'the most intelligent'.
On the other hand, the adverb menos can mean 'less' or 'least'. For instance, 'menos dinero' means 'less money' and 'el menos importante' means 'the least important'. So, the correct option is A) less, least.
