Correct Answer is: A
The best way to combine the two sentences is to use a comma and a coordinating conjunction. "And" is a logical connector, since the second sentence explains the consequences of the action mentioned in the first sentence. The other options don’t flow as well, either because they don’t use correct punctuation or because they use a connector that doesn’t make sense in the context.
