In this scenario, when a positively charged glass rod is brought near the positively charged electroscope, the positive charges on the electroscope (particularly on the cap) will be repelled by the positively charged glass rod. This will cause some of the positive charges on the cap to move down to the leaves, resulting in a decrease in the divergence of the leaves.

However, if the charge on the glass rod is significantly higher than that of the electroscope, it could momentarily increase the divergence before decreasing it due to the redistribution of charges.

So, considering the general trend, the correct answer would be:

A. decrease

the answer is A, the divergence will decrese because positive charges repel each other
