← HistoryWhich effect accompanied the Han Dynasty military's increased use of cast iron trigger mechanisms in crossbows?
A)Increased bolt velocity and range✓
B)More complex aiming reticles required
C)Reduced tension required for firing
D)Improved corrosion resistance in the field
💡 Explanation
Increased reliability and strength enabled stronger bows, which improved performance; therefore, increased bolt velocity and range directly resulted from cast iron's material properties improving projectile launch, rather than requiring more complex sighting due to altered acoustics or corrosion effects influencing mechanism longevity.
