Read the following poem and answer the question that follows :

In Those Days

In those days - they were long ago-
The snow was cold, the night was black.
I licked from my cracked lips
A snowflake, as I looked back

Through branches, the last uneasy snow.
Your shadow, there in the light, was still.
In a little the light went out.
I went on, stumbling_till at last the hill

Hid the house. And, yawning,
In bed in my room, alone,
I would look out: over the quilted
Rooftops, the clear stars shone.

How poor and miserable we were,
How seldom together!
And yet after so long one thinks:
In those days everything was better. 

What does the poet mean by the phrase "quilted roof tops"?

Roof top covered with snow

The correct answer is Option (2) - Roof top covered with snow

Detailed reasoning:

Roof top with a quilt on it
This is incorrect. The poet is not referring to an actual quilt placed on a roof. The phrase is used in a figurative way.

Roof top covered with snow
This is the correct answer. Snow lying softly on roofs looks like a white quilt spread over them. The poet uses the word quilted to create this visual image of snow-covered roof tops.

A house with many quilts in it
This is incorrect. The line does not talk about the inside of the house or the number of quilts.

People sleeping under quilts on roof tops
This is incorrect. The poem describes cold winter nights, not people sleeping on rooftops.

So, quilted roof tops means roof tops covered with snow.
