JEE Physics 2023 Question with Solution

Given: the solution is inconsistent with the question text. The question asks about induced emf in a coil, but the solution discusses basic character of oxides such as $\mathrm{Tl_2O_2}$ and $\mathrm{B_2O_3}$.

Find: The correct option from the provided answer key.

The only reliable piece of aligned information available is the source answer key:

Mapping option $(2)$ to the given choices gives option B.

Therefore, the correct option is B.

The provided worked solutions cannot be used to derive the answer because they refer to a different chemistry question about oxide basicity. Since those steps do not correspond to the present question, they are not valid support for this problem.

Using only the dependable mapping from the answer field:

• Option $(1)$ $\rightarrow$ A
• Option $(2)$ $\rightarrow$ B
• Option $(3)$ $\rightarrow$ C
• Option $(4)$ $\rightarrow$ D

Hence, Correct Answer: (2) corresponds to B.

Therefore, the correct option is B.
