Answer:
Inertia Newtons First law
Explanation:
Usually
pH scale measures from 1 to 14
Purple colour indicates pH as 14
Hence it's an base
But it doesn't react with metals to form salts and hydrogen gas.
It's sure it's non metal but not base
One possibility is that it's Carbon compound or Graphite compound which reacts like base but a metal in real sometimes
To solve the problem it is necessary to refer to the definition of entropy.
Entropy is defined aso

Where,
Heat exchange
T = Temperature
Since the heat exchange is conserved and it is an isothermal process where the temperature remains constant the change in entropy remains the same, ie
(Reamins same)
Therefore the correct answer is C.
