Understanding the Timetable
To determine which subject is taught by B, let's analyze the information provided step by step.
1. Teacher Assignments
- A teaches Mathematics, which is not in the first period.
- D teaches Physics in an even-numbered period (2 or 4).
- E teaches in the first period.
- C teaches Chemistry but not in the first or last periods.
2. Period Assignments
- Since E is assigned the first period, this means:
- Period 1: E (subject unknown)
- Hindi is taught in the last period (Period 5).
3. Analyzing Chemistry and Mathematics
- Chemistry is taught in an odd period and precedes Mathematics. Since Mathematics cannot be in Period 1 (E is there) or Period 5 (Hindi is there), it can only be in Period 2, 3, or 4.
- C teaches Chemistry, which cannot be Period 1 or Period 5. Therefore, Chemistry must be in Period 3 (the only odd period left). This allows:
- Period 3: C (Chemistry)
- Period 4: A (Mathematics)
4. Assigning Physics to D
- D, teaching Physics, must therefore be in Period 2 (the only even period left):
- Period 2: D (Physics)
5. Finalizing the Timetable
- Period 1: E (subject unknown)
- Period 2: D (Physics)
- Period 3: C (Chemistry)
- Period 4: A (Mathematics)
- Period 5: (last) Hindi
As E is the only teacher left for Period 1 and Hindi is in Period 5, E must teach Biology.
Conclusion
Thus, the final assignments are:
- Period 1: E (Biology)
- Period 2: D (Physics)
- Period 3: C (Chemistry)
- Period 4: A (Mathematics)
- Period 5: B (Hindi)
Therefore, the subject taught by B is Hindi. The correct answer is option 'D'.

- Period 3: C (Chemistry)
- Period 4: A (Mathematics)
- Period 5: (last) Hindi
As E is the only teacher left for Period 1 and Hindi is in Period 5, E must teach Biology.
Conclusion
Thus, the final assignments are:
- Period 1: E (Biology)
- Period 2: D (Physics)
- Period 3: C (Chemistry)
- Period 4: A (Mathematics)
- Period 5: B (Hindi)
Therefore, the subject taught by B is Hindi. The correct answer is option 'D'.
