For the following question, match the key event of meiosis with the stages listed below.
i. prophase i v. prophase ii
ii. metaphase i vi. metaphase ii
iii. anaphase i vii. anaphase ii
iv. telophase i viii. telophase ii
synaptonemal complexes form or are still present.
a)i only
b)i and iv only
c)i, ii, iii, and iv only
d)i and viii only
e)ii and vi only

A)I only

Explanation:

The synaptonemal complex is formed during the prophase 1 of meiosis. The synaptonemal complex is a s a protein structure that is formed between the homologous chromosomes that form a bivalent.  This structure binds and holds homologous chromosomes together and allows crossing over and genetic recombination between them. Crossing over and recombination occur in prophase 1, therefore, the synaptonemal complex disintegrates before the end of prophase 1.

answer; i believe its (ovulation);

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.
