At a triple point all three phases (i.e. solid, liquid and) coexist. Or we can define the temperature any substance at which substance withstand three phases called triple point. For water triple point is 0. So we can calculate it in K and R.

The triple point of water is 0.01c.
The option to choose is the incorrect one, since 0c = 273k = 32F = 492R, then only A is wrong.
So option A is the answer.
The option to choose is the incorrect one, since 0c = 273k = 32F = 492R, then only A is wrong.
So option A is the answer.

Triple point of water: 0 deg C.
Conversion:
0 C = 0+273 = 273K.
0 C = 32 F because T(F) = 5/9*T(C)+32.
T(R) = T(F) + 459.67.
So the remaining option is A.
Conversion:
0 C = 0+273 = 273K.
0 C = 32 F because T(F) = 5/9*T(C)+32.
T(R) = T(F) + 459.67.
So the remaining option is A.

Triple point of water is 0.01 deg c.
0 C = 273.15 K.
0.01 =273.16 K.
APPROXIMATE ANSWER WILL BE 273 K.
0 C = 273.15 K.
0.01 =273.16 K.
APPROXIMATE ANSWER WILL BE 273 K.

Triple point of water:
At 0° C = 273 K.
= 492 R.
= 32 F.
At 0° C = 273 K.
= 492 R.
= 32 F.

R stands for Rankine.
So, R = (C*1.8) + 491.67.
So, R = (C*1.8) + 491.67.

For Kelvin we do not mention degree (sign).
