Final answer:
The subset with no element in the context of a set containing Mango, Guava, and Lemon is called the empty set, which is a subset of every set including this one, making option D) the correct answer.
Step-by-step explanation:
The question is asking about the concept of subsets in the context of set theory, a part of mathematics. Specifically, it is asking about the subset with no elements, which is known as the empty set or null set. In mathematical terms, the empty set is a subset of every set, which means it is a subset of the set containing Mango, Guava, and Lemon. Therefore, the correct answer is D) There is no subset with no element because an empty set itself is the subset with no elements within this context.
