Which symbol corresponds to the answer "Λ"?

The symbol "Λ" is associated with the Greek letter Lambda. In the Greek alphabet, Lambda is the 11th letter and is commonly represented by the uppercase "Λ" and the lowercase "λ." Lambda is used in various contexts, including mathematics, physics, and engineering, often serving as a symbol for wavelength, eigenvalues, and more.

The other symbols listed correspond to different Greek letters: Theta (Θ), which is the 8th letter; Mu (Μ), which is the 12th letter; and Delta (Δ), which is the 4th letter. Each of these symbols has its unique significance and applications, but none represent the same character or sound as Lambda. Therefore, choosing Lambda as the answer aligns with the symbol "Λ."
