Solution

A. Hello foo and bin

Explanation

• The format() method is used to format the string by replacing the curly braces {} with the provided arguments in the specified order.
• In this case, the string "Hello {} and {}" has two placeholders.
• The first {} is replaced by the string 'foo', and the second {} is replaced by the string 'bin'.
• The resulting string is then printed, producing the output "Hello foo and bin".
