If it is raining then the grass is wet
and it's converse will be
If the grass is wet then it is raining
which is false converse
now, we will check each options
option-A:
If two lines are co-planar, then they are parallel
Converse:
If they are parallel, then two lines are co-planar
This is FALSE
option-B:
If x = 5, then x > 4
converse:
If x > 4, then x = 5
it is TRUE
option-C:
If an animal is a robin, then it is a bird
Converse:
If it is a bird, then an animal is a robin
this is FALSE
option-D:
If three points are collinear, then they are coplanar.
converse:
If they are co-planar, then three points are collinear
this is FALSE
