Final answer:
ABC Corp and XYZ Corp have a valid contract based on the elements of offer, acceptance, consideration, capacity, and legality. Mo's offer was accepted by ABC Corp's Director of Sales through a signed purchase order, fulfilling the requirement for mutual agreement. Both parties provided consideration, and there were no capacity or legality issues mentioned in the question.
Step-by-step explanation:
ABC Corp and XYZ Corp do have a valid contract. A valid contract consists of several elements, including offer, acceptance, consideration, capacity, and legality. In this case, Mo from XYZ Corp made an offer to purchase 10 industrial ovens for a price of 10000 dirhams each. ABC Corp's Director of Sales responded with a counter-offer, which Mo accepted by signing the purchase order. This exchange of offers and acceptance indicates a mutual agreement and therefore forms a valid contract between ABC Corp and XYZ Corp.
Furthermore, both parties provided consideration, which is something of value exchanged between the parties. ABC Corp agreed to supply the ovens, and XYZ Corp agreed to pay the price of 11000 dirhams per unit. The consideration on both sides fulfills another requirement for a valid contract.
It's important to note that there was no mention of any capacity or legality issues in the question provided. Therefore, assuming that both parties have the legal capacity to enter into a contract, and there are no illegal terms or actions involved, the contract between ABC Corp and XYZ Corp is valid.
