- A-II, B-I, C-III, D-IV
- A-III, B-I, C-IV, D-II
The Correct Option is D
Solution and Explanation
To match List I with List II regarding parts of the human eye, let us evaluate the options provided:
| List I | Description (List II) |
| Fovea | Point of greatest visual acuity or resolution |
| Iris | Visible coloured portion of eye that regulates diameter of pupil |
| Blind spot | Point where optic nerve leaves the eyeball and photoreceptor cells are absent |
| Sclera | External layer of eye formed of dense connective tissue |
Explanation:
- Fovea is known for its role in providing high visual acuity and resolution. Thus, it matches with "Point of greatest visual acuity or resolution." (III)
- Iris is the colored part of the eye responsible for adjusting the pupil size. This description aligns with "Visible coloured portion of eye that regulates diameter of pupil." (I)
- Blind spot is the point where the optic nerve exits the eye, and no photoreceptor cells are present, making it match "Point where optic nerve leaves the eyeball and photoreceptor cells are absent." (IV)
- Sclera is the tough, external layer of the eye, which corresponds to "External layer of eye formed of dense connective tissue." (II)
Based on the analysis, the correct matches are:
A-III: Fovea - Point of greatest visual acuity or resolution
B-I: Iris - Visible coloured portion of eye that regulates diameter of pupil
C-IV: Blind spot - Point where optic nerve leaves the eyeball and photoreceptor cells are absent
D-II: Sclera - External layer of eye formed of dense connective tissue
Therefore, the correct matching option is:

A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]
