Solution

The correct option is C Newlands' law of octaves
Elements have been arranged in the following sequence on the basis of their increasing atomic masses.
$F, N a, M g, A l, S i, P, S, C l$ & $K$

Law of octaves is given by the English chemist J.A.R. Newlands in 1865.
It states that if chemical elements are arranged according to increasing atomic weight, similar physical and chemical properties occur after each interval of seven elements.

Newlands was the first to detect a periodic pattern in the properties of the elements and anticipated later developments of the periodic law.
