Answer: D

Explanation:

From the output, we can see the current power level setting for the 802.11 bgn (2.4Ghz tab) is set at 5. Based on the following table from Cisco, that would mean the output power is 3 mW:

Here is the power conversion table to go from mW to 3bm:

So, with a power level setting of 5, the output power is 3mW, or 5 dbm. A power level of 4 would increase it to 6mW, or 8 dbm.
