The correct option is I, II, and III, as all these statements reflect the constitutional protections afforded to the Governor and members of the State Legislature in India. Statement I is based on Article 361 of the Constitution, which provides that the Governor is not answerable to any court for the exercise of powers or duties, ensuring independence in performing constitutional functions. Statement II, also under Article 361, protects the Governor from criminal proceedings during their term, thereby upholding the dignity of the office. Statement III relates to the principle of parliamentary privilege, which allows legislators to speak freely without fear of legal repercussions, safeguarding the integrity of legislative debates. These protections ensure that members can perform their duties effectively without external threats or pressures, maintaining the stability of the democratic process.
