When an 802.11a node broadcasts within the range of an 802.11g access point, there are a few things that could happen depending on the configuration of the access point and the capabilities of the node.

First, it's important to understand that 802.11a and 802.11g are two different wireless standards operating on different frequencies. 802.11a operates in the 5 GHz band, while 802.11g operates in the 2.4 GHz band.

If the 802.11g access point is configured to allow both 2.4 GHz and 5 GHz clients, and the 802.11a node is within range of the access point, the node should be able to connect to the access point. However, the node will only be able to operate at 802.11g speeds, as that is the standard being used by the access point.

If the access point is configured to only allow 2.4 GHz clients, then the 802.11a node will not be able to connect to the access point. This is because the node is operating on a different frequency band than the access point is configured for.

If the access point is configured to only allow 5 GHz clients, then the 802.11a node should be able to connect to the access point. However, the node will only be able to operate at 802.11a speeds, as that is the standard being used by the node.

In terms of the answer choices given:

A. The access point transmits, but the node is unable to receive. This answer is incorrect because if the access point is within range of the 802.11a node and is configured to allow 5 GHz clients, the node should be able to receive the transmission.

B. A connection occurs. This answer is partially correct, as a connection could occur if the access point is configured to allow both 2.4 GHz and 5 GHz clients, and the 802.11a node is within range of the access point. However, it's important to note that the node will only be able to operate at 802.11g speeds.

C. Both the node and the access point are unable to transmit. This answer is incorrect because if the access point is within range of the 802.11a node and is configured to allow 5 GHz clients, both the node and the access point should be able to transmit.

D. The node transmits, but the access point is unable to receive. This answer is incorrect because if the access point is within range of the 802.11a node and is configured to allow 5 GHz clients, the access point should be able to receive transmissions from the node.
