Explanation:

Electrochemical degradation affects rubber components like vehicle belts and hoses by causing chemical changes that weaken the rubber, potentially leading to tiny holes or structural weakening. Option b is incorrect as degradation wouldn't polish the surface. Option c is wrong because degradation reduces resistance, not enhances it. Option d relates to sound (likely from belts/hoses issues but not a direct effect of electrochemical degradation on the rubber itself, while option a directly describes the material degradation.

Answer:

a) Development of tiny holes or weakening of the rubber
