Easygoing is to apathetic as:a. Vigorous is to boring b. Emotional is to angry c. Pleasant is to nastyd. Lively is to energeti

The question is asking for an analogy. The relationship between the words in the first pair (easygoing and apathetic) is that they are both related to a lack of intensity or concern, but 'apathetic' is a more extreme version.

So, we need to find a pair of words where the second word is a more extreme version of the first.

a. Vigorous is to boring - This pair doesn't fit because 'boring' is not a more extreme version of 'vigorous'. They are opposites.

b. Emotional is to angry - This pair doesn't fit because 'angry' is not a more extreme version of 'emotional'. Anger is just one type of emotion.

c. Pleasant is to nasty - This pair doesn't fit because 'nasty' is not a more extreme version of 'pleasant'. They are opposites.

d. Lively is to energetic - This pair fits because 'energetic' can be seen as a more extreme version of 'lively'.

So, the answer is d. Lively is to energetic.
