Option B is correct because the expression 'burn in her blood' refers to having a passionate desire or a burning conviction. The context explains that a dream begins with a passion for a particular interest, and if it is still burning in your blood, it means you are deeply committed to realising it and ready to take the plunge. It does not mean to make her angry, cause physical pain, or become violent.

Sentence: The ambition to serve the nation seemed to burn in his blood, motivating him to work tirelessly for the community.
