Question

Choose the appropriate form of the verb:
Ann isn't free on Saturday. She___________ (work).

• A. will work
• B. is working
• C. was working
• D. has worked

Answer 1

The correct option is B is working

Sometimes, speakers use the present continuous tense to indicate that something will or will not happen in the near future, here, the action of working this Saturday. The present continuous is formed using am/is/are + present participle.(root verb+ing). Hence, Option B is correct.

The rest of the options either indicate that the action has already happened (Options C and D) or that the action will happen in distant and indefinite future (Option A), hence they're incorrect.
