Question

Which answer is a correctly punctuated compound sentence?

A.

B.
This shovel is old and rusty it is good enough, however, for the little bit of gardening we do.

C.
This shovel is old and rusty but it is good enough for the little bit of gardening we do.

D.
This shovel is old and rusty it is good enough; however, for the little bit of gardening we do.

Answer 1

A is correct.
B's mistake is hard to see, but it is there.
C has no punctuation where it's needed.
D sounds like this: "This shovel is old and rusty it is good enough. However, for the little bit of gardening we do." It sounds rushed in the beginning and the mark doesn't help.
