Give me answer is enough

What is the best result after simplifying the following function using Karnaugh map? F = PQRS + PQRS + PQRS + PORS A. F = PQS + PQS = 8. F = PQ F = QRS + QRS D. F = QS = Based on the given table with characters and their respective ASCII codes, what do you think is the most likely method to convert an uppercase letter of the alphabet to lowercase?

Add 32 to the uppercase's ASCII code. It is not possible to convert an uppercase letter to its lowercase using ASCII codes. Subtract 32 from the uppercase's ASCII code. D. The following is the first four rows of a partial truth table showing the patterns of a count-up counter's bits D, C, B, and A, and the inputs to their respective J-K flip-flops.
