What is a hydrocarbon?

  1. a) Wetness in the atmosphere

  2. b) An organic compound containing only carbon and hydrogen

  3. c) A severe tropical cyclone usually with heavy rains and winds

  4. d) Of or relating to or used in the production of electricity by waterpower

The correct answer is: b) An organic compound containing only carbon and hydrogen

A hydrocarbon is a compound exclusively made up of carbon and hydrogen atoms. This means that options A, C, and D are incorrect because they do not accurately describe a hydrocarbon. Option A refers to humidity or water vapor in the air, option B mentions a type of storm, and option D refers to a method of electricity production. So, if we compare these options to the definition of a hydrocarbon, we can see that they do not fit. Therefore, B is the best and only correct option.
