Answer:
Option C, 12, 6
Explanation:
The number of chromosome and DNA molecule are interpreted through the number of functional centromere and chromatids respectively at each phase of the cell division.
However, the DNA number only changes in the S phase of the cell division as replication occurs in this phase only.
Hence, after meiosis I two daughter cells will be formed with half the chromosome number i.e 3 and number of DNA is equal to 12.
Now, till metaphase II no change occurs. Now at anaphase II DNA remains same while the chromosome number increases to 6
Thus, the correct answer is option C

Weathering is process in which the rock breaks down into due to physical and chemical processes. It leads to wearing and tearing in the rocks. Weathering can be of three types physical weathering, chemical weathering and biological weathering.
Thermal stress weathering or insolation weathering occurs in places where there is a large change in daily temperatures. It causes the peeling off of the outer layer of the rocks.
