Geometry question please help

Because two of the sides are identical in each triangle, that means the 3rd side would also be the same.
You could use the SSS Posulate only, since no angles are known.
Answer:
The correct answer is second option
By SSS only
Step-by-step explanation:
From the figure we can see that, two triangles
ΔMNP and ΔMOP
The given information's are,
1). NP ≅ OM
2). MN ≅ PO
To find the correct option
To prove SSS congruence we need three sides .
To prove SAS congruence we need two sides and an angle between these two sides.
Here we have only three sides are given
1). NP ≅ OM ( given)
2). MN ≅ PO (given)
3). MP ≅ MP (Common)
Therefore the correct answer is second option
