CAGR signifies Compound Annual Growth Rate. It is computed using the formula:
\[
\text{CAGR} = \left(\dfrac{\text{Final Value}}{\text{Initial Value}}\right)^{\frac{1}{n}} - 1
\]
In this context, Final Value = ₹ 25,000, Initial Value = ₹ 5,000, and $n = 4$ years.
\[
\text{CAGR} = \left(\dfrac{25000}{5000}\right)^{\frac{1}{4}} - 1 = (5)^{0.25} - 1
\]
Given that $(5)^{0.25} = 1.4953$,
CAGR = $1.4953 - 1 = 0.4953$, which is equivalent to $49.53%$.
Hence, the correct option is (A).
