1."Do"(a)
'Do' is the auxiliary verb used to form present simple questions with 'you'. We say 'Do you like...?' 'Are' would need a verb ending in -ing (continuous). 'Have' would need a past participle (perfect). 'Does' is for third-person singular (he/she/it), not 'you'.
2."are"(b)
'Are' is the auxiliary verb for the present continuous with the plural subject 'they'. We say 'They are playing'. 'Is' is for singular subjects. 'Do' and 'have' cannot be used before a verb ending in -ing to form the continuous tense.
3."has"(c)
'Has' is the auxiliary verb for the present perfect with the third-person subject 'she'. We say 'She has finished'. 'Have' doesn't agree with 'she'. 'Is' and 'does' cannot be used before a past participle to form the present perfect.
4."didn't"(d)
'Didn't' is the auxiliary for past simple negatives. 'Last night' tells us this is past tense, so we need 'did not' (didn't). 'Don't' is present tense. 'Aren't' and 'weren't' need a verb ending in -ing, not the base form 'see'.
5."have"(a)
'Have' is a MAIN verb here meaning 'own' or 'possess'. It is NOT an auxiliary because there is no other verb it is helping. Compare: 'I have bought a bicycle' (auxiliary + past participle) vs 'I have a bicycle' (main verb). 'Has' doesn't agree with 'I'.
