Which object has the highest temperature? (see chart below)

object kinetic energy of molecules(j)
a 1.50 x 10^4
b 1.73 x 10^5
c 2.73 x 10^3
d 5.06 x 10^4

answers:
(a)object c
(b)object a
(c)object b
(d)object d

I can't see the chart.

But by kinetic energy theory, the temperature is a measure of the average kinetic energy of the particles.

So a low kinetic energy would depict a low temperature and a high kinetic energy would depict a high temperature.

So from this theory the particle with the highest temperature would be the one with the highest kinetic energy.

And that is by b,  with a value of 1.73 x 10^5 J.

(c)object B

The rocks expand when there hot/warm  and contract when they are cold.

It is d, all the other ones say incorrect answer .
