Correct choice is (b) False

The explanation: The given statement is false. Annealing takes place after cold rolling. Two different annealing processes are used after cold rolling: continuous annealing (which results in a strong material with a fine grain structure) and batch annealing (which has a coarse grain structure but excellent formability).
