Its A because it does show them as realistic and simpliy that is natural
In both inference and observation, you have to monitor or observe something.
Here's one example, you can build on it:
Sherlock Holmes 'observed' the scene below him.
His 'inference' was based on the evidences given to him.
Here's the definition of both of them...
the action or process of closely observing or monitoring something or someone is called observation.
a conclusion reached on the basis of evidence and reasoning is inference.
A) He is too interested in money
and
B) “There is nothing on which it is so hard as poverty; and there is nothing it professes to condemn with such severity as the pursuit of wealth!”
Hope this helps chu
Have a great day
