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.

Let's look at why the other options are incorrect:

• Alliteration: Alliteration is the repetition of consonant sounds at the beginning of words (e.g., "Peter Piper picked a peck of pickled peppers"). There is no such repetition in the given expression.
• Personification: Personification is giving human qualities or abilities to inanimate objects or abstract ideas (e.g., "The wind whispered secrets"). Silence in the given expression is an abstract noun, but it is not given a human action in a way that suggests personification.
• Simile: A simile is a comparison between two unlike things using "like" or "as" (e.g., "as brave as a lion"). The given expression does not use "like" or "as" to make a comparison.
