Consider the following pairs:1. Apophis - An asteroid that will pass ...
1. Apophis - Correctly matched. Apophis is an asteroid that will pass close to Earth in 2029.
2. CERT-IN - Correctly matched. CERT-IN is an entity under the Ministry of Electronics and Information Technology.
3. Squalus hima - Correctly matched. Squalus hima is a new species of deep-water dogfish shark discovered in Kerala.
4. DART Mission - Incorrectly matched. The DART (Double Asteroid Redirection Test) mission is an initiative by NASA, not ISRO, aimed at studying and potentially deflecting asteroids.

Analysis of the Given Pairs
To determine how many pairs are correctly matched, let's examine each one closely:
1. Apophis
- Apophis is indeed an asteroid that is expected to make a close approach to Earth in 2029.
- **Correct Match.**
2. CERT-IN
- CERT-IN (Computer Emergency Response Team - India) is an entity under the Ministry of Electronics and Information Technology, responsible for cybersecurity incidents.
- **Correct Match.**
3. Squalus hima
- Squalus hima refers to a newly identified species of deep-water dogfish shark discovered off the coast of Kerala, India.
- **Correct Match.**
4. DART Mission
- The DART (Double Asteroid Redirection Test) Mission is actually initiated by NASA, not ISRO, and aims to test a method of planetary defense against asteroids.
- **Incorrect Match.**
Conclusion
- With three pairs correctly matched (1, 2, and 3) and one incorrect (4), the total number of correctly matched pairs is three.
- Therefore, the answer is option 'C': **Only three pairs.**
This analysis confirms the accuracy of the statement regarding the pairs, providing clarity on each entity's relevance and affiliation.
