The best and most correct answer among the choices provided by your question is the fourth choice or letter D "Oil is nonpolar, and water is polar."

Oil will not dissolve in water because water forms a polar covalent bond and oil forms a non-covalent bond. According to the U.S. Department of Energy, in chemistry molecules dissolve with other molecules that share similar characteristics.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

This question can be easily confused with. During the early times, organic compound are directly associated with living beings, people, plants and animals. That is somewhat true. The definition of organic compounds are compounds that contain carbon. So, it is true that most of the compounds in our body are organic. But you may confuse it to the abundance of elements in the body, which is oxygen. However, the most abundant element, besides carbon, in organic compounds is Hydrogen. You will notice this obviously in the organic compounds like alkanes, alkenes, alkynes, carbohydrates, lipids, hormones and proteins. Their general chemical formula usually involves Carbon and Hydrogen.

5.00 g Ca

Step 2: Identify Conversions

Molar mass of Ca - 40.08 g/mol

Step 3: Convert

Set up: $\displaystyle 5.00 \ g \ Ca(\frac{1 \ mol \ Ca}{40.08 \ g \ Ca})$
Multiply: $\displaystyle 0.12475 \ mol \ Ca$

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

0.12475 mol Ca ≈ 0.125 mol Ca
