Which sentence correctly combines two independent clauses to create a compound sentence?

i have over fifty pairs of shoes, i wear the same pair of comfortable flip-flops every day.
i have over fifty pairs of shoes; but i wear the same pair of comfortable flip-flops every day.
i have over fifty pairs of shoes, but i wear the same pair of comfortable flip-flops every day.
i have over fifty pairs of shoes however; i wear the same pair of comfortable flip-flops every day.

The correct answer is C. I have over fifty pairs of shoes, but I wear the same pair of comfortable flip-flops every day.
In order to connect these two clauses, you need to use the appropriate conjunction, which in this case is the word but. However, you also need to pay attention to punctuation - you need to place a COMMA in front of but, which you can see in example C.
A is incorrect because there is no conjunction at all and there has to be one; B is incorrect because semi-colon is found in front of but when there should be a comma; D is incorrect because the semi-colon should be in front of however rather than after it.

Its C just took the test! ;)
