To solve this question, we need to identify the part of the human eye responsible for image formation.
1. Understanding Eye Anatomy and Function:
- Cornea: Transparent front part of the eye that helps in focusing light.
- Crystalline Lens: A transparent, flexible structure that fine-tunes the focus of light rays onto the retina, thus forming a clear image.
- Aqueous Humor: The fluid between cornea and lens, helps maintain pressure and provides nutrients, but not directly involved in image formation.
- Iris: Controls the size of the pupil to regulate light entry, not involved in focusing or image formation.
2. Identifying the Correct Answer:
The crystalline lens focuses light rays onto the retina and is directly responsible for image formation in the eye.
Final Answer:
Option (B) Crystalline lens is correct.
