This question is related to parallel lines.

(1) AD || BC - This can tell us that Angle CAD = Angle BCA. (AC intersects the two parallel lines). However, this will not give us the exact degree measure of Angle CAD.

INSUFFICIENT

(2) Angle CAD = 35 degrees. With this information, we can't get the degree value for BCA.

INSUFFICIENT

(1) and (2) If AC is the intersection and AD||BC, and angle CAD= 35.. that makes angle BCA = 35 degrees.

Answer is Option C
