Answer

B. face the outside of the engine / face the inside of the engine Explanation 1. Understand piston and rod orientation The arrow on the piston usually points toward the **front of the engine**, while the rod dimple indicates the **bearing offset orientation**. For **right-side pistons**, the dimple typically faces the **outside** (to balance crankshaft offset). For **left-side pistons**, the dimple faces the **inside**. 2. Match to given options Right side: arrow (front), dimple (outside) → **faces outside of the engine**. Left side: arrow (front), dimple (inside) → **faces inside of the engine**.
