Which of the following completes jim's proof?

Jim makes the chart shown below to prove that triangle APD is congruent to triangle BPC: Statements Justifications In triangles APD and BPC; DP = PCSides of equilateral triangle DPC are equal In triangles APD and BPC; AD = BCSides of square ABCD are equal In triangles APD and BPC; angle ADP = angle BCPAngle ADC = angle BCD = 90° and angle ADP = angle BCP = 90° - 60° = 30° Triangles APD and BPC are congruent SSS postulate

True as the lakes are a marine body. also there's no difference in lake and ocean except for the size.
