Network of microfilaments and microtubules is classified as

The correct option is "active skeleton".

Step-by-Step Explanation:

1. Understanding the Components:
Microfilaments (made of actin protein) and microtubules (made of tubulin protein) are dynamic cellular structures. They are not static structures; rather, they constantly undergo polymerization and depolymerization, allowing cells to change shape, migrate, and transport materials internally.

2. Dynamic Nature and Activity:
Because this network is constantly active, consuming energy (like ATP and GTP) to reorganize, move organelles, and facilitate cell division, it functions as an active skeleton within the cell.

3. Distinguishing from other terms:
While commonly referred to as the cytoskeleton in general biology contexts, under specific classifications focusing on its dynamic, energy-consuming, and functional movement capabilities, it is classified as an active skeleton to emphasize its role in cellular motility and active structural rearrangement.
