Idiomatic phrases are expressions whose meaning cannot be deduced from the literal meaning of their individual words. The idiom "To be in doldrums" originates from nautical terminology, referring to a region of the ocean near the equator characterized by calm winds, which would leave sailing ships becalmed and unable to move. Figuratively, this translates to a state of stagnation or low spirits.

• Therefore, the correct meaning is To be in a stagnant or depressed state, implying a lack of progress, activity, or energy, often accompanied by feelings of gloom or despondency.
• To be excited is the direct opposite of being in the doldrums, which suggests a lack of enthusiasm.
• To be wealthy has no connection to the idiom's meaning, as it refers to financial status.
• To be angry describes an emotion, but the idiom itself describes a state of inactivity or depression, not necessarily anger, although one might feel angry due to being in the doldrums.
