情人节题库286不解

QUESTION 286
A host is attempting to send data to another host on a different network. What is the first action that
the sending host will take?
A.Drop the data.
B.Send the data frames to the default gateway.
C.Create an ARP request to get a MAC address for the receiving host.
D.Send a TCP SYN and wait for the SYN ACK with the IP address of the receiving host.

答案为C。

这个C感觉不大对啊。先发ARP没错，但是是去找网关的MAC，而不是找receiving host的MAC。

不知道有没有考过的知道B和C哪个更正确。我是看着哪个也不靠谱。
