Solution

The most appropriate option is (b) and (d). These two queries correctly use the SQL LIKE operator to filter for employees whose first names start with 'R' and end with 'I'.

Query (b) uses two LIKE clauses combined with an AND operator. The 'R%' pattern matches any string that starts with 'R', and the '%I' pattern matches any string that ends with 'I'.

Query (d) combines these two patterns into one, 'R%I', which matches any string that starts with 'R' and ends with 'I'.

The other queries are incorrect. Query (a) would match any name that contains the string 'RI' anywhere, not just at the start and end. Query (c) is not a valid SQL query, as it does not use the LIKE operator or any wildcards correctly.
