Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The diploid stage is multicellular and haploid gametes are formed, meiosis is gametic, giving rise to an independent haploid or gametic generation as in pteridophytes.
Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte. Mitotic divisions within the gametophyte are required to produce the gametes. The diploid sporophyte results from the fusion of two gametes.
Hence the correct answer is (A)

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
