Consider the following pairs with regard to sports awards: 1. Major Dhyan Chand Khel Ratna Award : For the most spectacular and outstanding performance by a sportsperson over period of last four years 2. Arjuna Award : For the lifetime achievement by a sportsperson 3. Dronacharya Award : To honour eminent coaches who have successfully trained sportspersons or teams 4. Rashtriya Khel Protsahan Puraskar : To recognize the contribution made by sportspersons even after their retirement How many of the above pairs are correctly matched?

1. Major Dhyan Chand Khel Ratna Award: This is India's highest sporting honour, awarded to a sportsperson for the "most spectacular and outstanding performance over a period of the previous four years" at the international level. Thus, Pair 1 is Correct.

2. Arjuna Award: This award is given to sportspersons for their "good performance consistently for the previous four years" and for showing qualities of leadership, sportsmanship, and a sense of discipline. It is not primarily for 'lifetime achievement'. Thus, Pair 2 is Incorrect.

3. Dronacharya Award: This award is presented to "eminent coaches who have successfully trained sportspersons or teams and enabled them to achieve outstanding results in international events". Thus, Pair 3 is Correct.

4. Rashtriya Khel Protsahan Puraskar: This award is given to "corporate entities (both in private and public sector) and individuals who have played a visible role in the area of sports promotion and development". It is not specifically to recognize the contribution made by sportspersons after their retirement. That would be more aligned with the Dhyan Chand Award for Lifetime Achievement in Sports and Games (a separate award from the Khel Ratna). Thus, Pair 4 is Incorrect.

Therefore, only two pairs are correctly matched.
