✔ 最佳答案
The answer is C.
The isotopes of the same element have the same chemical properties.
A. Refer to CH4 (methane). CD4 is a correct chemical formula.
B. Refer to C2H5OH (ethanol). C2D5OD is a correct chemical formula.
C. Refer to Ca(OH)2 (calcium hydroxide). CaOD is an incorrect chemical formula. It should be Ca(OH)2.
D. Refer to HCl (hydrogen chloride). DCl is a correct chemical formula.
(Note that DCL is incorrect, because the symbol of chlorine is Cl but not CL.)
