The correct Answer is:
### Step-by-Step Solution 1. **Understanding the Assertion**: The assertion states that "Copper-T is an effective contraceptive device in human females." - Copper-T is a type of intrauterine device (IUD) that is used for contraception. It is known for its effectiveness in preventing pregnancy. 2. **Understanding the Reason**: The reason provided is "Copper-T prevents passage of sperm from vagina upwards into fallopian tubes." - Copper-T works by releasing copper ions, which create an environment that is toxic to sperm. This prevents sperm from successfully traveling through the reproductive tract to fertilize an egg. 3. **Evaluating the Truth of the Assertion**: - The assertion is true because Copper-T is indeed an effective contraceptive method. It has been widely used and is recognized for its efficacy in preventing pregnancy. 4. **Evaluating the Truth of the Reason**: - The reason is also true. Copper-T does prevent the passage of sperm from the vagina into the fallopian tubes, which is essential for preventing fertilization. 5. **Determining the Relationship**: - Since both the assertion and reason are true, and the reason correctly explains why Copper-T is an effective contraceptive device, we conclude that the correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion. ### Final Answer The correct answer is: **Option 1** - Both assertion and reason are true, and the reason is the correct explanation of the assertion. ---
