Which navigational error increases when a chronometer's rate drifts due to temperature variations impacting balance wheel oscillations?

💡 Explanation

When a chronometer's rate drifts, the time recorded deviates from the true time because thermal expansion alters the balance wheel's period, leading to accumulated time errors. Therefore, inaccurate longitude is the consequence, rather than speed, tidal, or draft errors, which depend on different measurement methods.
