Explanation

Choice B is the best answer. This choice uses paired punctuation in the form of two commas to set off the nonessential phrase "in the process."

Choice A is incorrect. The phrase "in the process" is a nonessential element and needs to be set off with paired punctuation. We need a comma after "and" to match the one after "process." Choice C is incorrect. The phrase "in the process" is a nonessential element and needs to be set off with paired punctuation, so we would need a dash after "and" to match the one following "process." Choice D is incorrect. The phrase "in the process" is a nonessential element and needs to be set off with paired punctuation. We would need a comma after "process" to match the one following "and."
