Final answer:
Option A, "Pay to D or order P10,000 on or before Dec. 31,1997 (Sgd.E)", is the non-negotiable statement.
Step-by-step explanation:
The statement that is not negotiable is option A. "Pay to D or order P10,000 on or before Dec. 31,1997 (Sgd.E)". In negotiable instruments, certain requirements must be met. One of these requirements is that the instrument must be payable on demand or at a specific future time. Option A does not meet this requirement as it specifies a specific date for payment, making it non-negotiable.
