Explanation
"This is the best peach producing valley"
Grammatically awkward. It should be:
"This is the best peach-producing valley."
(Hyphenate "peach-producing" as it's a compound adjective.)
"I done matric in 2010"
Incorrect verb form. It should be:
"I did matric in 2010"
("Done" is the past participle; here we need the simple past, "did.")
"This is an utensil"
"An" is used before vowel sounds, not just vowels.
The correct sentence is: "This is a utensil."
Because "utensil" starts with a 'yoo' sound, which is a consonant sound.
So, since all the options have errors, the correct choice is:
"None of these"
