AD||BC
In ΔAOD and ΔCOB

AD = BC (opposite sides of a parallelogram)
ADO = CBO (Alternate angles)
Hence, these two triangles are congruent by the angle side angle congruency.
In the congruent triangle
AO = OC and
BO = OD (corresponding sides)
Therefore, parallelogram’s diagonals bisect each other.
Hence, option 1 is correct.
