The correct option is: Iodine and NaCl.
Sublimation is a process where a solid changes directly into a gas without passing through the liquid state. Substances like iodine and ammonium chloride, and camphor can sublimate, but sodium chloride (NaCl) does not. Since iodine and sodium chloride cannot be separated by sublimation (because sodium chloride does not sublimate).

Sublimation is the process of transition of a substance directly from the solid phase to the gaseous phase without passing through the intermediate liquid phase. The substances that can sublime are those which have a high vapor pressure at normal temperature and pressure.
In this question, we have to identify the substance which cannot be separated by sublimation. Let's analyze each option:
a) Iodine and NaCl: Iodine can sublime under normal conditions, whereas NaCl has a high melting point and cannot sublime. Therefore, we can separate iodine from NaCl by sublimation.
b) Iodine and Ammonium chloride: Iodine can sublime, and ammonium chloride can also sublime at a relatively low temperature. Therefore, we can separate iodine from ammonium chloride by sublimation.
c) Camphor and Sodium chloride: Camphor can sublime, whereas sodium chloride has a high melting point and cannot sublime. Therefore, we can separate camphor from sodium chloride by sublimation.
d) None of these: This option is incorrect as we have already identified substances that can be separated by sublimation.
Therefore, the correct answer is option B, which is "Iodine and Ammonium chloride." Ammonium chloride can sublime, but it decomposes upon heating, producing ammonia gas and hydrogen chloride gas. Hence, we cannot separate iodine from ammonium chloride by sublimation.
