<u>B. Microphone</u> helps Carol to use the speech recognition software.
<u>Explanation</u>:
A microphone is a hardware device which converts the sound waves in the air into electronic signals. The electrical signals are transferred to a recording medium. Four main types of microphones are as follows:
i) Cardioid
ii) Super cardioid
iii) Omni
iv) Figure 8
Handheld microphone can be used better with the home theater or a karaoke machine. The speech recognition software can be used with the help of microphone. Cabling problem can be avoided with the use of microphone, thus cable trip hazard can also be avoided.
It would be autosum your welcome:)

Answer:
def max_n(arr, n):
arr.sort()
i = len(arr)-n
return arr[i:]
Explanation:
Define a function called max_n that takes two parameters, an array and an integer
Sort the array
In order to get the last n largest values, we need to slice the array. To do that we need a starting point. Our starting point of slicing will be the "lentgh of the array - n". That means, if we start slicing from that index to the last in the sorted array, we will get the last n largest values.
Assume array is 10, 2, 444, 91 initially.
When we sort it, it becomes 2, 10, 91, 444
Now let's say we want last 2 largest values, our sliced array index should start from 2 and go until the end
i = 4 - 2 = 2 → arr[2:] will return us 91 and 444
