Directions: Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option 'No error' as the answer response. (Ignore errors of punctuation, if any).

It is high time the company updates (A)/ its cybersecurity protocols to prevent (B)/ data breaches and implemented (C)/ stricter access controls (D).

The correct option is A.

Explanation:
The structure "It is high time" (or "It is time") is used to express that an action should have been taken already. When followed by a subject and a verb clause, the verb must be in the past tense (past subjunctive) form, even though it refers to a present or future action.

In part (A) of the sentence, the verb "updates" is in the present simple tense, which is grammatically incorrect after "It is high time". It must be replaced with the past simple verb "updated". Notice that part (C) also correctly uses the past verb "implemented" in parallel with this structure.

Corrected Sentence:
"It is high time the company updated its cybersecurity protocols to prevent data breaches and implemented stricter access controls."
