(c) calcium
Explanation:
One of the major limitations of Newlands' law of octaves was that it was applicable to only lighter elements having atomic masses upto 40u, which is up to calcium. After calcium, the first and the eighth element did not have similar properties. For example, chromium (Cr) and yttrium (Y) are the first and the eighth element placed in the same column but they have entirely different properties.
Option C is the answer.
