A) 100 kVA
B) 86.6 kVA
C) 150 kVA
D) 157.7 kVA
Output Power
The amount of power, typically measured in watts, that a device, system, or process delivers to its load.
Open Delta
An open delta connection refers to a method of transformer connection used in electrical systems that employs two transformers to create a three-phase supply with a smaller capacity than a full delta connection.

Final Answer :
B
Explanation :
The output power of an open delta transformer configuration is approximately 86.6% of the combined rating of the two transformers. Therefore, for two 50 kVA transformers, the output power is 0.866 * (50 kVA + 50 kVA) = 86.6 kVA.
