B. The cycle of repetition shown by elements is similar to octave in music.
C. It could not hold good for elements heaver than calcium.
D. Many radioactive elements have not been discovered then

What aaronq suggested is correct. You'll notice that on the the contemporary Mendeleev's periodic table that, after calcium, the transition metals start. This isn't a coincidence in regards to Newland's law of octaves — his periodic table was essentially a periodic table that was mostly accurate up to the point where the transition metals (and d-orbitals) started. Here's an informative (although rather annoyingly commentated) video regarding the subject: http://www.youtube.com/watch?v=ahm61dGn0fw
