The correct option is D) The kidneys contain nephrons.

Explanation:

Option D is correct because each kidney comprises of millions of filtering units which are called nephrons. The nephrons contain the glomerulus and tubule. The glomerulus is involved in the filtration of the blood whereas the tubules transport the useful substances back to the blood and help in getting rid of waste material.

Other options like option B is false because the bladder does not connect the ureter. Each ureter connects the bladder to the kidneys of each side.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
