Identify the part of the seed from the given figure which is destined to form root when the seed germinates.

In a seed, the part that forms the root during germination is called the radicle, which is located at the base of the embryo. From the given figure, the part labeled C corresponds to the radicle.
\[ \begin{array}{|c|c|} \hline \textbf{Seed Part} & \textbf{Function} \\ \hline \text{Radicle (C)} & \text{Develops into the root} \\ \text{Plumule} & \text{Develops into the shoot} \\ \text{Cotyledons} & \text{Store food for the developing seedling} \\ \hline \end{array} \]
Thus, the correct answer is (3) C.
A full wave rectifier circuit with diodes (\(D_1\)) and (\(D_2\)) is shown in the figure. If input supply voltage \(V_{in} = 220 \sin(100 \pi t)\) volt, then at \(t = 15\) msec:
