Answer:
the doctor is a woman who wears trousers
Step-by-step explanation:
Rukmani and Nathan set out to the city in search of their son, Murugan. On getting to the doctor's house after they were directed there by a young boy in the street called Puli, the servants inform them that they know no one named Murugan.
The doctor comes in at this time and they are surprised to see that the doctor is a woman who wears trousers. She informs the couple that Murugan has not worked for her in the past two years. She also directs them to the new place where Murugan now worked.
