Appeared in: NVS Staff Nurse - 2022

Explanation

The idiom 'extracting oil from sand' refers to attempting a task that is inherently impossible or futile.
Literally, sand does not contain oil, so the act of trying to extract it is pointless.
Figuratively, this translates to any situation where a person is trying to achieve something that cannot be done.
Therefore, the expression means attempting or achieving the impossible.

Option A: This option is a nonsensical and literal interpretation that has no connection to the idiomatic meaning.
Option C: This relates to deception or dishonesty, which is a different concept. The idiom is about impossibility, not untruthfulness.
Option D: This is a purely literal interpretation. Idioms have figurative meanings that go beyond the literal words.
