Hint: Iodine is a covalent compound. A covalent compound easily dissolves in a nonpolar solvent where an ionic compound dissolves in a polar solvent.
Complete Step by Step Answer:
Iodine gas readily dissolves in potassium iodide and forms a compound called potassium triiodide. The reaction can be given as follows:
$KI+{{I}_{2}}\to K{{I}_{3}}$
Iodine is a covalent compound and the carbon tetrachloride is a non polar compound. Thus iodine gas easily dissolves in nonpolar carbon tetrachloride solution but it does not react with carbon tetrachloride solution.
Iodine does not dissolve in water or alcohol.
Thus the correct options are B and C.
Additional Information: Iodine is a halogen element. It has the symbol of $I$. It generally exists as a gas. It has the colour of violet blue. Iodine is generally obtained from seaweed.
Starch generally acts as an indicator in titration reactions to determine the end point of a titration. Iodine gas reacts with starch, an indicator gives blue colour.
Note: Carbon tetrachloride contains chlorine atoms which are more reactive than iodine. Thus iodine can not replace the chlorine atom and does not react with it.
