(c) Endothermic processes are never spontaneous .

(d) exothermic process are always spontaneous .​

Answer 1

Hi !!

Spontaneity reaction depends on tendency to acquire minimum energy state and maximum randomness . for a spontaneous process in an isolated system the change in entropy .

Since option (B) is correct option .

for a spontaneous process in an isolated system , the change in entropy is positive. ✔✔

Hope it helps you !
