Answer
Brief Explanations:
The original sentences have a simple structure. The second option uses a subordinating conjunction "Although" to vary the sentence pattern. It shows a contrast between the chores (milking cows and feeding chickens) and her enjoyment of living on the farm, which is a good way to vary the pattern without changing the meaning. The first option combines the first two sentences but loses the contrast. The third option changes the emphasis. The fourth option has an incorrect logical relationship ("when" implies a time - related condition which is not the case here).
Answer:
Although Anna has to milk the cows and feed the chickens, she enjoys living on a farm.
