Explanation:
Constitutional guarantees can be described or explained as legal measures that protect basic or fundamental rights of the citizens.
some of the known basic or fundamental rights of the citizen of a country as mandated by law are
* the rights are freedom of speech,
* the right to a fair and public trial,
* the right to due process,
*the right to vote freely,
* the right to worship freely.
