Idiomatic Phrases: “To take the bull by the horns” means:

Idiomatic phrases are expressions whose meaning cannot be understood from the ordinary meaning of their individual words. The idiom "to take the bull by the horns" metaphorically describes confronting a difficult, dangerous, or unpleasant situation directly and courageously, much like a bullfighter would face a bull. Therefore, "To face a difficulty directly" is the correct answer, as it perfectly captures this sense of bold confrontation.

• "To avoid a problem" is incorrect because it implies evasion, which is the opposite of taking a problem head-on.
• "To run away" is also incorrect, suggesting retreat rather than direct engagement.
• "To create a problem" is wrong because the idiom refers to dealing with an existing challenge, not originating one.
