Correct answer is (b) False

For explanation: The given statement is false. The yield of chemical pulp is less than that of mechanical pulp. It is about one-half that of the mechanical process. It is because all the wood fiber (both cellulose and lignin) is utilized. This contrasts with several chemical processes where the lignin is dissolved to varying degrees.
