For Kelvin we do not mention degree (sign).

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.

32 rankine = -255.372222 degrees Celsius.

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.

Triple point of water:

At 0° C = 273 K.
= 492 R.
= 32 F.

Correct answer is 32F.

What is R?

Pratiksha said: (Sep 12, 2019)  
R stands for Rankine.

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

Answer is A.

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.
