Explanation

The customer requirement describes numbers with 'no discernible mathematical progression' - this is the definition of pseudo-random output (as opposed to sequential or patterned numbers). The requirement is for a Java-based system to generate these numbers on demand. Option B correctly restates this: a pseudo-random number generator invoked by the existing Java program when needed. Option A is incorrect because seeding a PRNG with the same value every time produces the same sequence, which is deterministic and predictable - the opposite of what is needed. Option C incorrectly specifies 'truly random' numbers (which require a hardware entropy source) and incorrectly ties randomness to PKI certificates, which serve authentication not entropy. Option D omits the critical detail that the PRNG must be invoked by the existing Java program and drops the specificity of 'corporate customers' without addressing the actual integration requirement.
