Before a cell can divide, its genetic information, must be copied.

That is true because otherwise there would be no genetic material to go into the new copy.

For lower level biology, A is correct. Without genetic information, a cell can't carry out any protein production and would die. So, if you're going to divide a cell, you need at least 2 sets of DNA.
However, cells can divide without copying DNA. Erythrocytes have no nucleus and no DNA. Technically, replication of DNA is not vital to cellular division - it just normally happens.

True - this process is Interphase in Mitosis/Meiosis.
[Interphase
DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin.
The nuclear membrane is still intact to protect the DNA molecules from undergoing mutation.]

true, so that the parent cell can pass on its traits to the daughter cells..
