Correct choice is 3

Step-by-step explanation:

Two intersecting planes intersect in line consisting of all common points of both planes. You cna name this line knowing at least two common points of these two lines.

1 picture shows that planes PQS and PRS intersect in PS (common points are P and S).

2 picture shows that planes PRS and PQR intersect in PR (common points are P and R).

3 picture shows that planes PQR and QRS intersect in QR (common points are Q and R).

4 picture shows that planes PQR and PQS intersect in QP (common points are P and Q).
