what happens during meiosis 1?

(a)chromosome pairs separate and are distributed into new sex cells.
(b)chromosome pairs remain together when new sex cells are formed.
(c)two sex cells combine to form a single new cell.
(d)each sex cell copies itself to form four new chromosomes.

The Answer D sound logical however I’m not sure about the 4 new chromosomes

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
