NIMCET 2025 Paper

Suppose that:
- $\mathit{C}$ represents the set of all countries,
- $\mathit{R}$ represents the set of all countries that have at least one river flowing through them,
- $\mathit{M}$ represents the set of all countries that have at least one mountain, and
- $\mathit{D}$ represents the set of all countries that have at least one desert.
It is given that:
$\mathit{R}\cup \mathit{M}\cup \mathit{D}=\mathit{C}$ Which of the following represents the set of all countries that have either a mountain or a river, but do not have a desert?
(Here, ${\mathit{D}}^{\mathit{c}}$ denotes the complement of $\mathit{D}$ with respect to the universal set $\mathit{C}$.)
