Final answer:
The shipment of cell phones can be classified as a B) counteroffer.
Step-by-step explanation:
The shipment of 500 silver cell phones from Text/Talk Communications to Senior Mobile Inc. can be classified as a OPTION B:counteroffer.
In this scenario, Senior Mobile Inc. initially offered to buy 500 silver cell phones containing Bluetooth and biometric technology features. However, Text/Talk shipped 300 phones with Bluetooth and biometric technology and 200 phones with Bluetooth only technology, without notifying Senior Mobile.
Since the shipment deviates from the original offer by including a different product mix than what was originally agreed upon, it can be considered a counteroffer.
