The adjective <em>scant </em>implies that something is barely sufficient or enough, so from November to April it scarcely rains or snows, and the country is desirous for rainfall.
The rest of the options are incorrect because the sentences do not follow a parallel structure. Thus, it is more suitable to place an adjective like <em>thirsty </em>after the adjectives <em>chill </em>and <em>quiet </em>to describe the season.
