## CORE INFORMATION
✓ **Answer**: [Option C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Contraceptive methods and their mechanisms of action
	**Related Topics**: Intrauterine devices (IUDs), hormonal contraceptives, mechanism of action of contraceptives
	**Prerequisites**: Basic understanding of contraceptive methods and their physiological effects
## SOLUTION PATHWAY
**Given Information**:
		1. Oral steroidal contraceptive pills inhibit ovulation.
		2. IUDs are inserted by doctors and expert nurses in the uterus.
		3. Copper releasing IUDs make the uterus unsuitable for implantation and inhibit ovulation.
		4. Hormone releasing IUDs make the cervix hostile to sperm.
**Method & Steps**:
	1. Identify the claims related to each contraceptive method.
		Reasoning: Understanding the mechanism of each method is essential to determine correctness.
	2. Analyze the claim of the copper releasing IUDs.
		Working: Copper IUDs primarily prevent fertilization by creating an inflammatory reaction in the uterus and do not inhibit ovulation significantly.
		Key Point: They do not prevent ovulation but instead create an environment unsuitable for sperm and implantation.
	3. Confirm the action of hormone releasing IUDs.
		Result: Hormone releasing IUDs do indeed make the cervix hostile to sperm and also thicken cervical mucus.
		Verification: All other claims are accurately described.
## OPTION ANALYSIS
[A] ✓: Oral steroidal contraceptive pills inhibit ovulation correctly describes the mechanism of action.
[B] ✓: IUDs are accurately stated to be inserted by medical professionals.
[C] :x: Copper releasing IUDs prevent implantation but do not inhibit ovulation, making this statement incorrect.
[D] ✓: Hormone releasing IUDs correctly described their effect on the cervix.
## LEARNING AIDS
	**Common Mistakes**:
		1. Misunderstanding the mechanism of copper IUDs: Remember they do not suppress ovulation.
		2. Confusing the roles of hormonal vs. copper IUDs: Know their distinct actions clearly.
	**Quick Tips**:
		1. Associate oral contraceptives with ovulation inhibition and IUDs with prevention of sperm reaching the egg.
		2. Remember that copper IUDs create a hostile environment rather than directly inhibiting ovulation.
