1. 1.

   A galactic botanist collects four glowing liquid elixirs from a floating nebula forest and examines them under standard laboratory conditions. Elixir Alpha forms distinct layered bands with cloudy droplets that scatter a light beam unevenly, while Elixir Beta remains completely transparent, uniform in color and density throughout, and leaves no residue upon filtration. Elixir Gamma contains swirling crystalline flakes that settle to the bottom when left undisturbed, and Elixir Delta quickly separates into an oily surface film and a dense watery base. Which elixir is correctly classified as a homogeneous mixture?

   • A) Elixir Beta, because its components form a single continuous phase with identical composition and properties throughout.
   • B) Elixir Alpha, because the presence of cloudy droplets and light scattering confirms a uniform molecular arrangement.
   • C) Elixir Gamma, because the gradual settling of solid flakes under gravity demonstrates a stable single-phase solution.
   • D) Elixir Delta, because the spontaneous separation into two distinct liquid layers is a defining feature of homogeneous mixtures.
