A census table contains data from the 2020 census with one row for each person in the US including their gender, occupation, age.

There are an index on the gender column, one on the age column, and one on the occupation column.

For the query

select  from census where gender='F' and occupation='CEO' and age<55

which index would give the better performance?

A. Use the index on age and scan the rows from the index for gender and occupation.

B Since no one index can answer the query, do a linear scan of the table.

C. Use the index on gender and then scan the rows from the index for age and occupation

D. Use the index on occupation and then scan the rows from the index for gender and age.
