Choose the correct answer from the option given below:
For reaction and reagent matching:
• Focus on identifying the reagents specific to each reaction’s mechanism.
• Recall key reagents used for reductions, substitutions, or rearrangements in named reactions.
- Hoffmann Degradation Reaction: This reaction uses Br2 and NaOH to convert amides into amines. Reagent: (III).
- Clemenson Reduction: This reaction reduces ketones or aldehydes to alkanes using Zn-Hg in HCl. Reagent: (IV).
- Cannizzaro Reaction: This reaction involves disproportionation of aldehydes without α-hydrogen in concentrated alkali. Reagent: (I).
- Reimer-Tiemann Reaction: This reaction introduces a −CHO group to phenols using CHCl3 and NaOH. Reagent: (II).

Let \( y = f(x) \) be the solution of the differential equation
\[ \frac{dy}{dx} + 3y \tan^2 x + 3y = \sec^2 x \]
such that \( f(0) = \frac{e^3}{3} + 1 \), then \( f\left( \frac{\pi}{4} \right) \) is equal to:
