Question

Please help! Which are acceptable names for the line?

Answer 1

so answers B and C are correct, but D isn't 
and just thinking about it B can't be correct either because it has a point on a line and letter A i constructed a new red plane that also have AU thus AU is not unique so im goining with (C)

Answer 2

'B' and 'D' are correct.
'C' isn't, and we don't know about 'A' because you left it out.
