The heat from the current flow will cause damage that can be much more serious than the ______________ might suggest.

• A. internal injuries
• B. external injuries
• C. electrical burns
• D. structural damage

Answer: (B)

When current flows through the body, it heats tissues along its path. That heat can cause deep, internal damage even if the outside looks relatively normal. The danger lies in hidden injuries to muscles, nerves, organs, and the heart, which may be far more serious than any outward wound suggests. So the statement emphasizes that the heat damage from electrical current can be much greater than the external injuries might indicate. Even a small or inconspicuous surface mark can accompany significant internal injury, which is why electrical injuries require careful medical evaluation and monitoring.

The other terms don’t fit the contrast as naturally. Saying internal injuries might suggest the opposite relationship, and electrical burns or structural damage don’t capture the common reality that deep, internal harm can outpace what you can see on the surface. External injuries is the natural contrast to the hidden, internal damage often caused by electrical current.
