The Correct Option is B
Solution and Explanation
Tuple Relational Calculus (TRC) uses quantifiers such as Existential (*) and Universal (V) to specify conditions on tuples in a relation. These quantifiers are fundamental in expressing queries in TRC, similar to the use of quantifiers in predicate logic. Domain Relational Calculus uses a different set of rules for expressing queries.
