\nThe correct answer is B) Emerald.
\n<\/section>\n
\nEmerald is a variety of the mineral beryl, with the chemical formula Be\u2083Al\u2082(SiO\u2083)\u2086. The chemical composition clearly shows the presence of Beryllium (Be) metal. The green color of emerald comes from trace amounts of chromium or vanadium within the crystal lattice.
\n<\/section>\n
\nLet’s look at the composition of the other gemstones:
\n– Topaz: Aluminium and fluorine silicate (Al\u2082SiO\u2084(F,OH)\u2082). Contains Aluminium, Silicon, Oxygen, Fluorine, Hydrogen.
\n– Ruby and Blue Sapphire: Both are varieties of the mineral corundum, which is aluminium oxide (Al\u2082O\u2083). Ruby is colored by chromium, and sapphire by iron and titanium.
\nThus, out of the given options, only Emerald contains beryllium.
