The correct options are

When Charles X became the king of France in 1830, he promised to rule according to the Charter of 1814 and introduced progressive changes in laws like abolishing censorship. Despite all this, he was not very popular among the people of France because he was a conservative and favoured old Nobles who had fled France during the French Revolution. He also passed repressive ordinances that included terms like suspending freedom of the press, modifying the electoral laws in such a way that three-fourths of the people eligible to vote were now deprived of their rights.
