Within the first three minutes of the universe, the elements that were formed include Hydrogen, Helium, and Lithium.

Here's the step-by-step reasoning:

1. Big Bang Nucleosynthesis: This process occurred within the first few minutes of the universe's existence.
2. Formation of Protons and Neutrons: Initially, the universe was extremely hot and dense, allowing protons and neutrons to form.
3. Fusion Reactions: As the universe expanded and cooled, these protons and neutrons underwent fusion reactions.
4. Hydrogen: The simplest and most abundant element formed was Hydrogen, consisting of one proton.
5. Helium: Through further fusion, some of the Hydrogen nuclei combined to form Helium.
6. Lithium: In smaller quantities, some Helium nuclei combined with Hydrogen to form Lithium.

Therefore, the correct elements formed within the first three minutes of the universe are Hydrogen, Helium, and Lithium.
