(c)
Centroid 
is a rational point. Orthocentre is intersection point of two altitudes which will bear rational coefficients when expressed as 
straight line. So, orthocentre is also rational. Circumcentre is intersection point of two perpendicular bisectors which will bear rational coefficient when expressed as a straight line. So, circumcentre is also rational. But statement 2 is not true as in equilateral triangle all the centres coincide
