The right answer is A) Trisomy
Aberrant karyotypes containing an abnormal number of chromosomes are known in the human species. The best-known (and most common) chromosomal abnormality is trisomy 21, which is responsible for Down syndrome (mongolism). There are others such as Turner syndrome (woman with a single X chromosome) or Klinefelter syndrome (man XXY).
These abnormalities originate from the non-disjunction of the chromosomes of a pair of homologues during metaphase I of meiosis. At the end of division I, a daughter cell contains the two chromosomes of the pair considered and the other cell does not contain a chromosome of this pair. A similar result can be obtained during a bad distribution of chromatids during anaphase II.
After fertilization from a gamete of this type, a trisomy or a monosomy is obtained.

Answer:
After a motion is proposed, if the motion requires a second and none is immediately offered, the chair of the body will usually ask, "Is there a second?" If no second is obtained within a few moments of proposing the motion, then the motion is not considered by the assembly, and is treated as though it was never offered. Such a motion may be introduced again at any later time.

There are two descriptions of denial wherein; (1) he denies that what he does cannot be controlled and (2) he denies that what he does leaves a negative impact in his life. This patient falls to the latter description of denial.
