How many Process Builder processes can be active simultaneously on a single object?

Correct answer: Unlimited

Option C is correct because Salesforce does not impose a hard platform limit on the number of active Process Builder processes per object; multiple processes can be active on the same object simultaneously, though Salesforce recommends consolidating them to manage order-of-execution complexity. Option A, 10, is not a documented platform limit for active processes per object. Option B, 5, is also not a documented platform limit for this feature. Option D, 50, is similarly not a documented limit; the correct understanding from Salesforce documentation is that there is no enforced numeric cap on active processes per object.
