Exp) Option c is the correct answer.

Fundamental Rights can be suspended during the operation of a National Emergency except the rights guaranteed by Articles 20 and 21. Further, the six rights guaranteed by Article 19 can be suspended only when emergency is declared on the grounds of war or external aggression (i.e., external emergency) and not on the ground of armed rebellion (i.e., internal emergency).

Option a is incorrect. Their application to the members of armed forces, paramilitary forces, police forces, intelligence agencies and analogous services can be restricted or abrogated by the Parliament (Article 33).

Option b is incorrect. Fundamental Rights are defended and guaranteed by the Supreme Court. Hence, the aggrieved person can directly go to the Supreme Court, not necessarily by way of appeal against the judgement of the high courts.

Option d is incorrect. Most of Fundamental Rights are directly enforceable (self-executory) while a few of them can be enforced on the basis of a law made for giving effect to them. Such a law can be made only by the Parliament and not by state legislatures so that uniformity throughout the country is maintained (Article 35).
