This question is asking us to calculate the amount of nitrogen in a 25 kg bag of urea fertilizer, which contains 46% nitrogen.

To solve this problem, we need to find 46% of 25 kg.

To calculate the amount of nitrogen, we can multiply the weight of the bag (25 kg) by the percentage of nitrogen (46% or 0.46).

So, 25 kg x 0.46 = 11.5 kg.

Therefore, the amount of nitrogen in a 25 kg bag of urea fertilizer is 11.5 kg.

The correct answer is Option A: 11.5 kg.
