The correct answer is:
a. Deals with constitutional matters only.
The Constitutional Court in South Africa is the highest court in the country for all constitutional matters. Its primary function is to protect and enforce the Constitution of South Africa. The court has the power to declare legislation and executive acts unconstitutional and invalid, and it also has the authority to develop common law principles in line with the Constitution. The court does not impose sentences, amend acts, or get overruled by the High Courts in South Africa.
