• Meaning of the sentence: The sentence asks if banks can protect user data from very smart and advanced cyber attacks when new digital money is introduced without good security. • Why Option B is correct: Sophisticated means highly complex or advanced. Cyber threats in the modern digital banking world are complex, making this the right fit. Why other options are wrong: • Resilient means able to recover quickly from damage. We usually describe systems or people as resilient, not cyber threats. • Primitive means very simple or basic, which would not be hard for banks to stop. • Dormant means inactive or sleeping, which means they are not an immediate active danger. • Redundant means unnecessary or extra, which does not logically fit a threat.
