Result
Your answer: —  Â·  Correct: C
Explanation

The chemical symbols for elements are often derived from their Latin names. Gold has the symbol Au, which comes from its Latin name 'aurum'. Tin is represented by the symbol Sn, derived from the Latin 'stannum' [3]. Lead is represented by the symbol Pb, originating from the Latin 'plumbum' [2]. These symbols are standardized in the periodic table to facilitate international scientific communication [1]. Other options provided in the question include symbols for different elements: Ga represents Gallium, Sb represents Antimony, and At represents Astatine [3]. Therefore, the correct sequence for gold, tin, and lead is Au, Sn, and Pb respectively, as confirmed by standard chemical nomenclature and the reactivity series.
