The answer is <span>B) three chromosomes in any one set.
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes (so choice C. does not indicate a genetic problem). There are in total 46 chromosomes (23 pairs in 2 copies), that differs in lengths (so choice D. does not indicate a genetic problem). Speaking of a pair of sex chromosomes, there could be two X chromosomes in females or one X and one Y chromosome in males (so choice A. </span><span>does not indicate a genetic problem).
But, having three chromosomes in </span>any one set suggests a presence of trisomy, which is <span> a condition in which an extra copy
of some chromosome is present. This results in a genetic disorder.</span>
The answer is pollination
Modern GM is quicker and more precise than long term plant breeding.

Solution
It is given that the membrane is permeable to both salt and water.
Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.
As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.
Thus water will move from side A to side B and Salt will move from side B to side A.
Hence, option C is correct
