Which statement correctly explains the relation between oxidation and reduction?

Answer and explanation

Correct answer: Both often occur together in the same reaction

Oxidation and reduction are complementary processes. In a redox reaction, one substance loses electrons or gains oxygen and is oxidised, while another substance gains electrons or loses oxygen and is reduced. These changes occur simultaneously because electrons transferred by one species are accepted by another. Therefore option A is correct; a precipitate is not required, and redox changes are chemical rather than merely physical.
