Answer 1

C. Elements with similar properties are grouped together in a pattern.

The periodic table is organized based on the periodic law, which states that elements with similar chemical and physical properties recur at regular intervals when they are arranged by increasing atomic number. This results in the grouping of elements into columns (groups or families) that share similar characteristics.
