Answer 1

Answer: (A), (B), (D)

The correct options are
A Used in large and small scale industries.
B There is no neutral in delta connection.
D It is used in transmission to distant places.

Delta connection is desirable for transmission to distant places because only three wires are required here instead four wires are required for star connection.. There is no neutral in the delta connection.
In large and small-scale industries, the primary and secondary coils are in delta winding.
