Answer:
The correct answer is option A. Allusion
Explanation:
An allusion is used in rhetoric to refer to something indirectly, that is, by referring to it.
In this case the title "An Idle Fellow" refers to inactivity, who has been the faithful companion during the author's life.
He even describes himself as a person who does not like to do anything, and his "idle fellow" is said inactivity.
The boy's rendition of his late father's painting was an absolute monstrosity. It was unveiled right beside the old man's grave to a crowd of dishevelled bystanders, the ladies holding their billowing skirts down and the men scratching at their unkempt beards. It wasn't a particularly sacrilegious artwork, but the crowd would say otherwise. Hands jumped to mouths to keep a scream bottled in, eyes widened to the point of tearing. They'd never seen something quite like it.
The only noun I know derived from the verb to entomb would be the noun entombment.
It is an abstract noun, which means that it doesn't have a physical shape - you cannot touch it or smell it, just like with love, or hate, or happiness. Entombment is the process of placing a dead body into a tomb, or a grave.
