The correct option is C Weep
'Wish' is the base form of the verb, its past and past participle form is 'wished'. It is a regular verb because we've simply added an -ed to the base form of the verb to form the past and past participle form. Similarly, 'whine' and 'whip' too are regular verbs as an -ed is added to form their past and past participle forms.
Therefore, option A 'wish', option C 'whine' and option D 'whip' are incorrect.
The correct option is option B, 'weep'. It is an irregular verb as its past and past participle forms are 'wept' and have not been formed with the addition of -ed at the end of the base verb 'weep'.
