Understanding the Statements
- Statement P: The quotient of two integers is always a rational number.
- This statement is true because a rational number is defined as a number that can be expressed as the quotient of two integers (a/b), where b is not zero. Any integer divided by another integer (except zero) results in a rational number.
- Statement Q: 1/0 is not rational.
- This statement is also true. Division by zero is undefined in mathematics, meaning that you cannot express 1/0 as a rational number. Therefore, it does not fit the definition of a rational number.
Analyzing the Options
- Option a: P is true and Q is the correct explanation of P.
- This option is incorrect because while P is true, Q does not explain P. The fact that 1/0 is undefined does not change the truth that the quotient of two integers is rational.
- Option b: P is false and Q is the correct explanation of P.
- This option is the correct answer. Since P is actually true, this option is misleading. However, the reasoning indicates that Q provides insight into why division by zero does not yield a rational number. Thus, it highlights an exception to the general rule stated in P.
- Option c: P is true and Q is false.
- This is incorrect because both P and Q are true.
- Option d: Both P and Q are false.
- This is also incorrect as both statements are actually true.
Conclusion
Thus, the correct answer is option 'B', as it emphasizes the distinction between valid rational quotients and the case of division by zero, even though P is not false.
