The correct option is
C plays
In order to fill in the blank with the most appropriate helping verb, we must understand the 'subject and verb agreement'. A subject is a person, thing, or a concept, in a sentence. A sentence always describes a person, thing or a concept and that is called 'subject' of the sentence. The rest of the sentence is a complement (which has the object in it). A subject and a verb should always agree in a sentence. If the subject is singular (example: Raj), the verb will also be singular (does). If the subject is plural (We), the verb will also be plural (do).As the given sentence asks us to fill in the blank with a verb that agrees with the subject and not with the complement, we will focus on the subject only.
NOTE: Though 'team' is a plural subject, 'Krishna' is the main subject and it is singular. Hence, we will need a singular verb.
Option A - 'Play' is a plural verb and hence, option A is incorrect.
Option B - 'To play' is an infinitive with the marker 'to'. 'Everyday' suggests that the sentence is in simple present tense. Hence, we will use a verb in present tense and not an infinitive. Thus option B is incorrect.
Option D - 'Has played' is used to represent an action in present perfect tense. As the given sentence has the word 'everyday', we must use simple present tense only. Hence, option D is incorrect.
Option C - 'Plays' is a singular verb and can be used here as it represents simple present tense. Hence, option C is the correct answer.
'Krishna, along with the team plays cricket everyday.'
