Answer:
The correct answer is option d. "More money on education that they did without vouchers".
Step-by-step explanation:
In the education voucher case, the government reduces funding from public schools and are given to private schools in the form of scholarships to students that are not able to pay the private schools. Therefore, parents who sent their child to the public schools end paying more money on education that they did without vouchers as the funding for the public schools is reduced to pay for the vouchers.
