Answer:

b. The Hello timer as configured on the root switch.

Explanation:

There are differrent timers in a switch. The root switch is the only forwarding switch in a network, while non root switches blocks traffic to prevent looping of BPDUs in the network. Since the root switch is the only forwarding switch, all timing configuration comes from or is based on the configuration in the root.

The hello timer is no exception as the nonroot switch only sends 802.1D DTP hello BPDU messages forwarded to it by the root switch and its frequency depends on the root switch hello timer.
