The correct option is B Irregular verbs
Regular verbs form the past and past participle tense with the addition of -ed at the end of the base form of the verb. Hence, option A, 'regular verbs' is incorrect.
The infinitive is the base of a verb, often followed by 'to'. It does not form a past participle tense. Therefore, option C is incorrect.
Option D, will also be incorrect as gerund is that form of the verb which ends in -ing, but plays the role of a noun. It is not used to form the past participle tense.
The correct option is option B as the past and past participle form of an irregular verb is not formed with the addition of -ed at the end of the base form of the verb.
