I have two sets of str objects, each containing given names.

a = {'Maria', 'Hilda', 'Virginia'} b = {'Virginia', 'Maria', 'del', 'Carmen'}

Choose the expression that uses set operators to return a new set with the names that are in common in both sets. The names that are in common for both sets are "Maria and "Virginia.

Select one:

a. a | b

b. a & b

c. a ^ b

d. a - b
