Answer:
A. It would block DNA replication
Explanation:

B) it IS NOT true because the formation of the spindle is a different independent process, and occurs in the presence of chromosomes with crosslinked strands.
C) it IS NOT true because condensation of the chromosomes occurs when teir DNA strands are crosslinked.
