| List-I | List-II | ||
| A | Rhizopus | I | Mushroom |
| B | Ustilago | II | Smut fungus |
| C | Puccinia | III | Bread mould |
| D | Agaricus | IV | Rust fungus |
To solve the problem of matching List I with List II, we need to understand the characteristics of each item in List I and how they relate to List II. Here is a breakdown of the matching process:
| 1. | Rhizopus (List I) is commonly known as bread mould. This matches with "Bread mould" (III) in List II. |
| 2. | Ustilago (List I) is known as smut fungus. This matches with "Smut fungus" (II) in List II. |
| 3. | Puccinia (List I) is referred to as rust fungus. This matches with "Rust fungus" (IV) in List II. |
| 4. | Agaricus (List I) is the scientific name for the common mushroom. This matches with "Mushroom" (I) in List II. |
Thus, the correct matching is as follows: A-III, B-II, C-IV, D-I.
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
The current passing through the battery in the given circuit, is:
