B,C Correct answer
Explanation

Birds sitting on power lines don't get electrocuted because they only contact one wire. For current to flow through a body and cause harm, there must be a potential difference and a complete circuit path. A bird on one wire is at the same potential as that wire, so no current flows through its body. Danger occurs only if the bird simultaneously touches two wires at different potentials or a wire and the ground.
