The correct answer is option A.
Concept:
WHERE Clause:
The WHERE clause is used to retrieve data that meet some specified conditions. 
Consider the following relation.
Table: Customers

The IN operator is used with the WHERE clause to match values in a C_country like India or USA.
SQL Query:
Select *
from Customers
where C_Country ='Inida';
Output:
The select query prints the complete row of the relationship when the condition is true. So when the C_country is 'India' then Customer relation prints the entire row of the database.
Hence the correct answer is B.
