Which configuration ensures that the switch is always the root for VLAN 750?

The correct answer is D. Switch(config)#spanning-tree vlan 750 priority 0. Although the spanning-tree vlan 10 root primary command will ensure a switch will have a bridge priority value lower than other bridges introduced to the network, the spanning-tree vlan 10 priority 0 command ensures the bridge priority takes precedence over all other priorities.
