Select the most appropriate option to substitute the underlined segment in the given sentence.
Now, the maid is clean the floor which is in the second stair.
Show answer & explanation
Correct answer: A
Explanation
The sentence requires the Present Continuous Tense because of the keyword "Now," which indicates an action happening at this very moment.
The Error: The original segment "is clean" is incorrect because "clean" is being used as a verb, but it is in the base form. After "is," you must use the -ing form to show continuous action.
for Present Continuous is Subject + is/am/are + verb-ing.Since "the maid" is singular, we use "is cleaning."
B) cleaning: Missing the auxiliary verb "is."
C) has cleaned: This is Present Perfect, used for an action that is already finished.
D) cleans: This is Simple Present, used for habits or routines, not actions happening "Now."
