Solution

The correct option is B Electrical Discharge Machining (EDM)
1. EDM has the lowest specific power requirement and can achieve sufficient accuracy.

2. ECM has the highest metal removal rate.

3. USM and AJM have low MRR and combined with high tool wear, are used for non-metal cutting.

4. LBM and EBM have high penetration rates with low MRR and. therefore, are commonly used for micro drilling, sheet cutting.
