(A) There is no psychoactive substance to which more people are physically addicted than are addicted to caffeine. [Correct. It is supported by the last line.]
(B) A physical addiction to a particular psychoactive substance will typically give rise to diverse psychological symptoms. [Only symptoms related with caffine are given. So, this is very broad generalisation. Incorrect]
(C) Not all substances to which people can become physically addicted are psychoactive. [Such refernce is not included in the passage. Narrow in scope. Incorrect]
