Explanation:
After completion of meiosis-I, the cell undergoes meiosis-II. During meiosis-I, the cell goes through two rounds of division - the first division (meiosis-I) and the second division (meiosis-II). Let's break down the process step by step to understand why the correct answer is '14'.

Meiosis-I:
During meiosis-I, the cell undergoes DNA replication in the S phase of interphase. Then, in the first division, the cell separates homologous chromosomes, resulting in two daughter cells. Each daughter cell contains half the number of chromosomes as the parent cell.

Given that there are 14 chromosomes in the cell after completion of meiosis-I, this means that each of the two daughter cells resulting from meiosis-I would have 7 chromosomes each.

Meiosis-II:
Each of the daughter cells from meiosis-I enters meiosis-II. In meiosis-II, the two daughter cells undergo another round of division, similar to mitosis. This division separates the sister chromatids, resulting in four haploid daughter cells.

Since each of the daughter cells from meiosis-I had 7 chromosomes, after meiosis-II, each of the four resulting daughter cells would also have 7 chromosomes each.

Therefore, the correct answer is '14' since the total number of chromosomes in the cell after completion of meiosis-II would be the sum of chromosomes in all four daughter cells, which is 7 + 7 + 7 + 7 = 28 chromosomes.

To summarize:
- After meiosis-I, each daughter cell has 7 chromosomes.
- After meiosis-II, each of the resulting daughter cells still has 7 chromosomes.
- Therefore, the total number of chromosomes in the cell after completion of meiosis-II is 4 × 7 = 28 chromosomes.

However, the given answer is '14', which seems to be incorrect. It is possible that there is a mistake in the question or answer options provided. The correct answer should be 28 chromosomes after completion of meiosis-II.
