Final answer:
CQL is close to SQL and supports prepared statements but does not support joins natively.
Step-by-step explanation:
The correct statements about CQL (Cassandra Query Language) which is related to the database technology are as follows: a) True - CQL is close to SQL in its syntax and readability, making it easier for those familiar with SQL to learn and use CQL. c) True - CQL does support prepared statements, which is a feature that allows for pre-compiling the queries and reusing them with different input parameters, improving efficiency and security. However, b) False - CQL does not natively support joins as you might expect in relational databases; instead, the database design in Cassandra is typically denormalized for performance reasons.
