6. Imagine a class named People with attributes infants (a list of infants) and m_boy and m_girls with the class static variable: m_boys + m_girls = len(infants). Consider how a method called add_infant(self, infant, is_boy) could be prepared. What is correct about this class static variable? O %3D a. If the variable is ever not correct, python will raise an error. O b. It must be correct after every line of add_infant is executed. O c. It must be correct before and after add_infant is executed. both a and b both a and c
