  1. wereCevap
  2. B
    was
  3. C
    has been
  4. D
    is

Cevap

were
The expression 'a number of' acts as a plural quantifier meaning 'many' or 'several', which grammatically requires a plural verb. Because the action occurred in the past ('yesterday's security audit'), the plural past-tense verb 'were' is the correct option.

Adım Adım Çözüm

1
Identify the head noun expression establishing subject-verb concord.
The subject begins with the indefinite quantifier expression 'a number of'.
In standard English concord rules, 'a number of' functions as a plural determiner meaning 'several' or 'many' and takes a plural verb.
2
Determine the required tense and number for the verb.
The temporal context 'yesterday's security audit' requires a past-tense verb, and plural concord requires 'were'.
Combining plural agreement with past-tense context yields 'were'.
