Solution

The correct option is D $C l, B r$
According to Newland Octave law, when elements are arranged in increasing atomic mass every eighth element has similar properties to the first element.
Further, the law did not apply to elements of higher atomic masses. So, the law was applicable till calcium.
Hence, $C l, B r$ does not apply to Newland Octave Rule.
