Fill in the blank with the correct word from the options given below…

The correct answer is Option (2) → from

"Take inspiration from":

• To take (or draw, get) inspiration means to get ideas or the urge to create something.
• The source of the ideas is introduced by from: one takes inspiration from a person, a place or a thing.
• This sentence: Pinterest is the source of the artist's ideas, so "took inspiration from Pinterest".
• Complete sentence: The graffiti artist took inspiration from Pinterest for the new installation project.
  Example: The poet took inspiration from the hills around her village.

Why the Other Options are Incorrect?

Option 1: by — Incorrect. "By" goes with the passive verb "be inspired by", not with the noun phrase "take inspiration".
Example: The film was inspired by a true story.

Option 3: in — Incorrect. One finds inspiration in something, but "take inspiration in" is not used.
Example: She found inspiration in her grandmother's stories.

Option 4: for — Incorrect. "For" shows purpose; the sentence already uses it correctly in "for the new installation project", but the source of the inspiration needs "from".
Example: He is saving money for a new laptop.

Contrast: one takes inspiration from a source, but one is inspired by it.
