Which of the Following Made It Unlikely That Texas Will

Which of the following made it unlikely that Texas will enact a personal income tax in the near future?

A) The Texas Constitution was amended in the 1990s to require that the voters approve of the creation of a state income tax, and that any money generated from it be used to support public education.
B) The Texas Constitution explicitly prohibits a personal income tax, and does not include any provision for creating a personal income tax.
C) The Texas Supreme Court ruled that the personal income tax that had been in place previously violated the Texas Constitution. Once a law has been declared unconstitutional by the Texas Supreme Court, it cannot be reintroduced.
D) The creation of any new forms of revenue, including a personal income tax, would require the support of three-fourths of both chambers of the legislature. In the current partisan polarized environment, it is nearly impossible to reach this threshold.
