| 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.

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is
