QID: NA623 no explanation given

Any help appreciated - I don't get why the answer isn't through the T1 link

[forumsupport]

Link-state routing protocols use link bandwidth in the best route calculation and the route through T3 has a higher bandwidth available, so it has the least path cost.

T1 = 1.544 Mbps
FastEthernet = 100 Mbps.
T3 = aggregation of 28 T1 circuits = 44.736 Mbps

@ all: which answer is the correct answer from the options, please?
