Without access to the specific text of paragraph 78, I can't provide a definitive answer. However, based on the general meaning of the word "leisure," it usually refers to free time when one is not working or engaged in other obligations, and is often associated with relaxation and enjoyment.
If you are looking for a meaning that aligns closely with this interpretation, "Relaxation" would likely be the best choice from the provided options. If you have the text of paragraph 78 or more context, I can offer more precise assistance.
