NOTE: The given sentence needs a verb in simple present tense, as the sentence is a general sentence. 'School education' is a singular subject and requires a singular auxiliary verb/verb form.
Option A - 'Need' is the plural form of the verb used with a plural subject. As the subject of the given sentence is singular, we can't use 'need' here. Hence, option A is incorrect.
Option C - 'Needing' is the participle form of the verb 'need'. As the given sentence is a general statement, we can't use 'needing' here. Also, in order to use a participle verb, we need an auxiliary verb as well. Hence, option C is incorrect.
Option D - 'Is need' is incorrect as the given sentence needs either an auxiliary or a verb in the singular form. Hence, option D is incorrect.
Option B - 'Needs' is the singular form of the auxiliary verb used with a singular subject. It helps to form the sentence in simple present tense, hence we can use 'needs' here. Thus option B is the correct answer.
'School education needs a drastic change.'
