Which mode is used for selective calling?(a) Mode A(b) Mode B(c) Mode

1.	Which mode is used for selective calling?(a) Mode A(b) Mode B(c) Mode C(d) Mode S
Answer» The correct option is (d) Mode S Best explanation: Different modes have its own unique features; mode A gives only identity, mode c gives identity and altitude, mode B is used in European operations and mode S is used for selective calling of transponders.
