Dauntless means showing fearlessness and determination, especially in the face of danger or difficulty. It describes someone who is bold, courageous, and not easily discouraged or frightened. Among the options, Brave clearly matches this idea of courage.

Brave means having or showing courage, especially when faced with danger, pain, or difficulty.Step 3: Compare the two meanings. A dauntless person is clearly a brave person, so these words are very close in meaning.Step 4: Check Option B: Insane. This means mentally ill or extremely foolish, which does not match the positive quality of fearless courage.Step 5: Check Option C: Playful. This means full of fun or high spirits, again unrelated to bravery.Step 6: Check Option D: Ugly. This refers to something or someone that is unpleasant in appearance and has nothing to do with courage.Step 7: Conclude that Brave is the correct synonym for Dauntless.

Verification / Alternative check:
Consider example sentences. One might say, The dauntless soldiers advanced despite heavy fire or She showed a dauntless spirit in fighting her illness. Replacing dauntless with brave gives The brave soldiers advanced despite heavy fire and She showed a brave spirit in fighting her illness, which preserves the meaning. On the other hand, using insane, playful, or ugly in these sentences makes them illogical or changes their meaning completely. This confirms that Brave is the right choice.

• Playful denotes a light hearted, fun loving behaviour and does not imply bravery.
• Ugly describes unattractive appearance and does not relate to a person is willingness to face danger.
