Correct option is (a) True

For explanation: The given statement is true. Groundwood pulp contains a considerable proportion (70%–80%) of fiber bundles, broken fibers and fines in addition to the individual fibers. The fibers are essentially wood with the original cell wall lignin intact. Therefore, they are very stiff and bulky, and does not collapse like the chemical pulp fibers.
