Her father ............. a) speaks English very fluent b) speaks English very fluently c) is speaking English very fluently d) is speaking English very fluent

To determine the correct answer among the given options, let’s analyze the grammatical structure of each choice.

1. Identify the Subject and Action: The subject is "Her father," and the action is the verb "speaks" or "is speaking."

2. Understanding Adverb Use: In English, adverbs modify verbs, adjectives, or other adverbs. The adverb form of "fluent" is "fluently," which means the action of speaking is done in a fluent manner.

3. Evaluating Each Option:

   • a) "speaks English very fluent" - Incorrect, as "fluent" is an adjective and should be replaced with "fluently."
   • b) "speaks English very fluently" - Correct, since it uses the adverb "fluently."
   • c) "is speaking English very fluently" - Also correct, as it uses the adverb "fluently" in the present continuous tense.
   • d) "is speaking English very fluent" - Incorrect, for the same reason as option a.

4. Final Decision: Options b) and c) are both correct grammatically; however, if only one option is allowed, option b) is more straightforward.

Final Answer

b) speaks English very fluently
