The correct answer is option B

When we analyse carefully we can see that PQR is mapped on to P'Q'R' by the rule




That is to say the <em>x-coordinates</em> are <em>negated</em>. Hence y-axis is the mirror line.
Since reflection is a rigid motion, the two triangles are congruent. That means the two triangles PQR and P'Q'R' are equal in all respect.
