Read the passage given below and answer the questions that follow by choosing the
answer from the given option
By the time our delayed train reached and I disembarked with my father and baby
Lavanya, it was well past midnight. It was cold, dark and foggy. My husband, Manas, who
was to receive us, was nowhere in sight. Soon the platform became deserted. Then, a burly
man approached us and offered to carry our bags. He wasn’t wearing the usual porter’s
red shirt and tag, and though I was wary, my father decided to hire him. Leaving Lavanya
and me with the man, my father went to look for Manas. I took a closer look at the man
and felt apprehensive. He was big and hairy, his face was pockmarked and his eyes looked
bloodshot.
Just then Lavanya, who had been sleeping in my arms, awoke, and turned to look
at the porter. He gave her a playful smile and held out his arms. I thought she’d start
crying and held her closer. But she smiled back and twisted herself out of my arms into
his. Now I was really scared. What if he ran away with my baby? He must have sensed my
fear and, even before I reached out to take Lavanya back, he handed her to me. Turning
around, he mumbled that though everyone was scared of him, yet my innocent baby had
accepted him. His eyes had tears in them. I didn’t know what to say.
At that moment my father returned with Manas, The man picked up our bags and
walked towards the car parking. As we followed him, I asked Manas to pay him a little
extra. But, having put our luggage in the car, the man refused to take payment from us.
Coming up to me, he placed his hand on my baby’s head for a moment as if to say, ‘God
bless you!’ and walked away.
