Meiosis II will have 
chromosomes.
Meiosis:
- Somatic cells divide during meiosis, a process in which the genetic makeup or quantity of chromosomes in the daughter cells is maintained.
- In sexually reproducing organisms, a kind of cell division known as meiosis results in a decrease in the number of chromosomes in gametes (the sex cells, or egg and sperm). Human body cells, also known as somatic cells, have two sets of chromosomes and are diploid (one from each parent).
- A single cell splits twice during the meiosis process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.

Answer:
Option (D).
Explanation:
Processivity of DNA polymerase may be defined as the number of nucleotides added in the single binding event. The synthesis phase of cell cycle is fully dependent on the processivity of DNA polymerase.
The processivity of DNA polymerase depends on the sliding clamp, domains of the DNA and the interaction of DNA with enzyme. Loss of hydrogen ion at 3'OH primer does not affect processivity but important for the nucleophile attack and also effect the catalytic property of enzyme.
Thus, the correct answer is option (D).
