Which of the following operations will transform a tetrahedron ABCD with vertices as listed below x y z A | 0 0 0 B 1 0 0 C0 1 0 D 0 0 2 into a tetrahedron ABCD with vertices as Ilisted below x y A 0 0 0 B 0 1 0 C0 0 1 D 2 0 0 up to suitable translation ? (a) A rotation aboutr axis by t/2, then a rotation about z axis by n/2 (b) A reflection in the xy plane, then a rotation about x axis by r/2 (c) Areflection in the yz plane, then a reflection in the xy plane (d) A rotation about y axis by t/2, then a reflection in the xz plane

see this... when u make a rotation about some axis then that axis is fixed...

I gave my best for helping u.. hope u will get it..

This is rotation about x axis by 90° so option b and d will transform.
Vaishnavi rajora
but in order to transform c and b we will again rotate about z axis by 90
