Which figure of speech (poetic device) has been used in the expression:

 the room was filled with a screaming silence.

Oxymoron

The correct answer is OPTION 1 Oxymoron.

Oxymoron is a figure of speech in which two contradictory terms are combined to create a new meaning. In the expression "the room was filled with a screaming silence," the two contradictory terms are "screaming" and "silence." This creates a sense of tension and unease, as the reader is forced to reconcile the two opposing ideas.

The other options are incorrect. Alliteration is the repetition of initial consonant sounds in a series of words. Personification is the attribution of human qualities to inanimate objects or animals. Simile is a comparison between two things using the words "like" or "as."
