But ordinary water is not used as moderator there are many types moderators like graphite, cd road as well as d2o.

I think ordinary water is more strong answer than graphite.

What property of water makes it a good moderator?

In nuclear reactors. There is. No participation of electrons. Only proton and neutron only. In this case, both graphite and heavy water (20. Atomic mass) are suggestible.
Both reduce the speed of neutrons.
Then, The probability of colliding nature of neutrons to uranium will increase.
In each collision, 3 neutrons released out of 3, two are absorbed by cadmium rods. Remaining 1 neutron speed will be controlled by graphite and heavy water.

Graphite moderating ratio is 170. It is a second best moderator first is D2O.

@S Kumur.
Why cadmium rods are used?
Why cadmium rods are used?

In nuclear reactor cadmium rod and D2O is used to moderate the electron to speed down the reaction.

Graphite is good nuclear reactor.

Moderator means to slow down the neutrons. With the help of graphite electrode.

Graphite is used in nuclear reaction.
