How Would You Respond to an Expectant Mother Who Claims

How would you respond to an expectant mother who claims that her eight-month-old foetus gets excited every time her unusually loud cell phone plays a custom ringtone of her recorded voice?

A) 'You may be correct, because by that age, the foetus may actually be hearing your voice.'
B) 'It is likely gas, since foetuses can't hear until they are out of the womb.'
C) 'If what you say is true, you are likely carrying a female because they develop a sense of hearing before males.'
D) 'Since foetuses have no memory, there is no way they would only respond to a specific phrase.'
