The correct answer is c. The three segments are AB, BC, and AC.
In the figure, segments are typically denoted by two endpoints. Therefore, the segments mentioned are:
AB - This is a segment with endpoints A and B.
BC - This is a segment with endpoints B and C.
AC - This is a segment with endpoints A and C.
Option (a) is incorrect because "BA" is not a valid segment in the figure; the order of the endpoints matters.
Option (b) is incorrect because it only mentions two segments (AB and BC), but the figure includes a third segment (AC).
Option (d) is incorrect because "CA" is not a valid segment in the figure; the order of the endpoints matters.
So, option (c) correctly identifies all three segments in the figure: AB, BC, and AC.
