Final answer:
Driving around the block is generally the easiest and safest method for making a turnabout as it uses basic driving maneuvers and is usually less risky than U-turns, three-point turns, or two-point turns.
Step-by-step explanation:
The easiest and safest method of making a turnabout is C. driving around the block. When evaluating the options given, it's important to consider the level of risk and difficulty associated with each maneuver. A U-turn requires a wide road and is prohibited in many areas due to its risk.
A three-point turn can be difficult in heavy traffic and requires a good command of the vehicle's controls and an understanding of spatial dynamics. A two-point turn can also be safe, but it involves reversing and can be risky in areas with poor visibility or high traffic.
Driving around the block, however, is typically the safest as it minimizes exposure to oncoming traffic and doesn't require specialized maneuvers. This option utilizes regular driving skills and adherence to traffic laws and control devices.
Therefore the correct answer is A. a two-point turn.
