Step 1: Understanding the sentence.
The sentence describes an action that has happened
very recently. The word
“just” indicates that the event occurred a moment ago. In English grammar, the
present perfect tense is commonly used to describe actions that have happened recently and are connected to the present time.
Step 2: Present perfect structure.
The structure of the present perfect tense is:
Subject + has/have + past participle.
In this sentence, the subject is
“It”, so we use
has. The past participle of
strike is
struck. Therefore the correct phrase becomes
“has just struck”.
Step 3: Checking the options.
- (A) had just struck: Past perfect tense; used for an action completed before another past action.
- (B) has just struck: Correct; present perfect tense indicates a recent action.
- (C) has been just striking: Incorrect continuous form.
- (D) is just struck: Grammatically incorrect structure.
Step 4: Conclusion.
Thus the correct sentence is:
It has just struck ten.
Final Answer: has just struck.
