Question

Identify the irregular verb from the verbs given below:

• A. Fill
• B. Filled
• C. Flee
• D. Filling

Answer 1

Answer: (C)

Flee

'Fill' is the base form of the verb, its past and past participle form is 'filled'. Fill is a regular verb as its past and past participle form is formed with the addition of -ed at the end of the base form of the verb.
Therefore, option A 'fill' and option B 'filled' are incorrect, whereas, filling is the continuous form of the verb 'fill', therefore option D is incorrect.
The correct option is option C, 'flee' as its past and past participle is 'fled'. It's an irregular verb as its past and past participle form is not formed with the addition of -ed at the end of the base form of the verb.
