Answer 1

Correct answer is (b) Groundwood

For explanation: Groundwood pulp is produced by forcing wood against a rapidly revolving grindstone. The heat generated by friction softens the lignin so that the fibers separate with very little damage. In this, practically all the wood fiber (both cellulose and lignin) is utilized.
