Correct option is B. A discovery in New Jersey actually contributed to the

early economic development of America and, in 1714, a worker uncovered a green rock containing copper.

Here, the use of conjunction 'and' is incorrect as it creates a kind of distortion which seems as if we are talking about two different things: rather then linking the two parts of the sentence, 'and' further disconnects it.

"When" seems better than "And". It clearly indicates the mentioned time. Thus B is the correct answer.
