Answer & Explanation
The correct answer is Option B: Low penetration coarse splatter & flat bead.
An excessively long arc results in increased voltage, leading to low penetration, unstable arc characteristics, and significant coarse splatter. The instability often produces a flat, uneven weld bead because the heat is not sufficiently concentrated to fuse the base metal effectively.
