Final answer:
The line with only non-continuous (stative) verbs is a) imply, recognize, prefer. These verbs describe states of being or emotions, which are not used in continuous tenses, unlike 'take' which is an action verb.
Step-by-step explanation:
To answer the question, we must choose the line with only non-continuous (stative) verbs. Stative verbs describe a static condition, state of being, or emotion, and are not used in continuous tenses. Analyzing the options provided:
a) imply, recognize, prefer
b) prefer, take, imply
c) recognize, prefer, doubt
d) doubt, imply, recognize
The verbs 'imply', 'recognize', and 'prefer' are all stative verbs because they represent states of mind or emotions, which are not actions in progress. Therefore, option a) imply, recognize, prefer is the line with only non-continuous (stative) verbs.
In contrast, 'take' is an action verb and thus does not fit the requirement for a line with only non-continuous verbs, eliminating option b). Options c) and d) have the same verbs as option a) and are therefore also lines with only stative verbs. However, as 'doubt' could sometimes be used in a continuous form depending on usage and context (e.g., 'I am doubting'), the best choice remains with 'prefer', 'imply', and 'recognize' as they are more definitively stative. Hence, the safest option is still a).
