If A(0,1,2), B(2,-1, 3) and C(1, -3, 1) are the vertices of a triangle, then its circumcentre and orthocenter are situated at a distance of

• A. 3 units
• B. 2 units
• C. $\frac{3}{2}units$
• D. $\frac{3}{\sqrt{2}}units$

Answer 1

The correct option is D $\frac{3}{\sqrt{2}}units$

ortho center- (2, -1, 3)
Circum center- $(\frac{1}{2},-1,\frac{3}{2})$
