D) All of the above.
All three options, pure water, gold, and table salt, are examples of pure substances. A pure substance is a type of matter that has a constant composition and cannot be separated into simpler components by physical means. In other words, it consists of only one type of particle or molecule.
A) Pure water is a compound made of water molecules (H2O) and does not contain any other substances.
B) Gold is an element, composed solely of gold atoms (Au).
C) Table salt (sodium chloride - NaCl) is also a compound, consisting of sodium and chlorine ions bonded together in a fixed ratio.
Since all the options are examples of pure substances, the correct answer is D) All of the above.
