Given Information:
- There are three friends - Mr. Dhoosar, Mr. Kalia, and Mr. Reddy.
- They are a History teacher, a Science teacher, and a Math teacher.
- They have different colored hairs - White, Black, and Red.
- Red-haired person is not a Math teacher.
- White-haired person doesn't teach Science.
- Black-haired person teaches Math or Science.

Analysis:
We need to determine who teaches History based on the given information.

Step 1: Identify the possible combinations of hair colors and subjects.

- Red-haired person cannot be a Math teacher.
- White-haired person cannot be a Science teacher.
- Black-haired person can be a Math or Science teacher.

- White-haired person doesn't teach Science. This eliminates possibility 2.

Step 3: Conclusion

- From step 2, we can conclude that possibility 3 is the only valid combination.
- Therefore, the Black-haired person teaches History.
