Correct option is C
The part of the sentence that contains the error is: “With cloud streaming, people can play games from a”.
· The error is in the use of the indefinite article "a" before "internet-connected device." It should be "an internet-connected device" because the word "internet" begins with a vowel sound.
· Correct sentence: With cloud streaming, people can play games from an internet-connected device, avoiding the need for pricey dedicated hardware such as a game console.
