As we know thermal conductivity of liquid decreases with increase in temperature so option B is correct.

Water is exception about the theory that k of liquid decreases with rise in temperature?

You are right @Avinash because due to hydrogen bonding it increases up to 113 C and then decreases with rise in temp.

In Liquids thermal conductivity decreases with increase in temperature (except water) due to decreases in density with increase in temperature.

Aluminium is also this kind of metal in which temperature increase then conductivity decrease.

Fusion curve of water has negative slope so that water is expands on freezing like that.

There is an exception to water. There is a temperature called anomalous temperature 4*c at which water behaves differently before it and after it.

For most liquids the thermal conductivity falls with increasing temperature but this occurs only above about 130°C in liquid water.

For liquids and solids, the thermal conductivity decreases with increase in temperature. But water is an exception, in the case of water the thermal conductivity increases with increase in temperature.
