A. Starts
B. Started
C. Have started
D. Has started

Answer 1

Hint:Simple past tense is utilized to communicate an activity finished before. It frequently happens with qualifiers or intensifier expressions of past time.
Some of the time, it is likewise utilized without an intensifier of time, where time might be either inferred or shown by the unique circumstance.

Complete answer:
"It's high time" is an articulation used to make recommendations when one feels that it's late for something to occur. In such sentences, the simple past tense type of verb is utilized to discuss the present or future. All in all, simple past tense can be utilized to discuss the present/future in expressions with time.

Let us look at the options and discuss the solution.
Option A:- 'Starts' is a simple present tense, much the same as the underlined action word "start". The lone distinction between the two is that the previous is utilized for the third individual 'he/she starts' though the last is utilized for a first and second individual: I, you, and so forth. Since it's in the present state, it isn't needed here. Henceforth option A is erroneous.
Option B:- "Started" is in the simple past tense and is utilized in sentences starting with 'The opportunity has already come and gone' to allude to right now. Subsequently, B is the right choice.
Option C:- 'Have started' is in the present perfect tense. It implies that the activity has recently been finished.
Option D:- Similarly, 'had begun' is in the past perfect tense and expresses that activity has finished before. In any case, the given sentence doesn't express a finished activity. The speaker means to make a recommendation. It is an incorrect option.

Hence the correct answer is option B.

Note:Past perfect tense depicts an activity finished before a specific moment in the past.
eg. I had met with a mishap in Delhi.
On the off chance that two activities occurred before, it very well might be important to show which activity happened sooner than the other. The past perfect tense describes one activity and another activity is described by the simple past tense. Eg - her mother was always grumbling.
