Which one of the following pairs is correctly matched?

The correct answer is D because at the time this question was framed, Sunil Gavaskar held the world record for the highest aggregate of runs in Test Cricket. He was the first batsman to score 10,000 runs and retired with 10,122 runs, which was the highest until it was later surpassed by Allan Border and others.

Regarding the other options: A is incorrect because while Jim Laker holds the record for most wickets in a single match 19 wickets, the term highest number of wickets usually refers to career totals, where Muttiah Muralitharan holds the record. B is incorrect because Brian Lara holds the record for the highest individual score in a Test innings 400 not out, but at the time of this question, Matthew Hayden had briefly overtaken Lara's previous record of 375. C is incorrect because the partnership of 576 runs by Jayasuriya and Mahanama was the highest at that time, but current records are often subject to change in historical contexts of such exams.

However, in the specific context of the UPSC paper this question was taken from, D was the officially accepted answer reflecting the contemporary records of that era.
