Step 1: Understand the constraints.
- Hindi is not scheduled on the first day.
- English is not scheduled before Hindi.
- Mathematics is scheduled one day after Physics.
- Biology is scheduled two days after Hindi.
- One day prior to Chemistry, there is no examination (i.e., Chemistry must be on the last day of the week).
- Only one examination can be scheduled per day.
- Sunday is not an off day.
Step 2: Analyzing the schedule.
- Since only one examination is scheduled per day, and there is no examination the day before Chemistry, it follows that Chemistry must be on the last day, Saturday.
- Since Biology is scheduled two days after Hindi, Biology must be on Friday, and Hindi must be on Wednesday.
- English must be scheduled after Hindi, and it can't be before Hindi. Therefore, English must be on Thursday.
- Mathematics must be scheduled one day after Physics, meaning Physics must be on Tuesday and Mathematics must be on Wednesday.
- Hindi, then, is on Wednesday, and the schedule is finalized.
Step 3: Conclusion.
Therefore, Physics is on the first day (Sunday), and Chemistry is on the last day (Saturday). Thus, the correct answer is (B).
