Correct option is (a) True

Explanation: The cope and drag pattern are similar to a split pattern. In addition to splitting the pattern, the cope and drag halves of the pattern along with the gating and risering systems are attached separately to the metal or wooden plates along with the alignment pins. Hence, they are called to cope and drag patterns.
