Select the correct projectile counterpart to complete the analogy: “Bow : Arrow :: Pistol : ?” Pick the item that stands to a pistol as an arrow stands to a bow.

Introduction / Context:
Equipment–projectile analogies pair a launching device with what it launches. A bow launches an arrow; a pistol launches a specific projectile used in firearms.

Given Data / Assumptions:

• Bow → launches arrow.
• Pistol → launches bullet (via a cartridge that includes bullet, case, powder, primer).
• The answer should name the projectile, not the device or action.

Concept / Approach:
Maintain “launcher : projectile” symmetry. For a pistol, the correct projectile term is “bullet.”

Step-by-Step Solution:
1) Identify the form of relation: device → projectile.2) Map pistol → bullet.3) Exclude actions or other weapons to keep the relation parallel.

Verification / Alternative check:
Basic firearms terminology confirms this mapping: rifles/pistols fire bullets; “gun” and “rifle” are devices, not projectiles; “shoot” is an action.

Why Other Options Are Wrong:

• Gun/Rifle: Launchers, not projectiles.
• Shoot: Verb/action, not a projectile.
• Magazine: Ammunition feeding component, not the projectile.

Common Pitfalls:
Confusing components of ammunition with the projectile or picking another device instead of the launched item.

Final Answer:
Bullet
