Why is radiocarbon dating not good for material more than 30,000 years old?

Because all animals emitted radiocarbon before that time

Because radiocarbon was not present anywhere before that time

Because the amount of C14 becomes almost immeasurably small in 30,000 years

Beacause carbon extraction was not known before 30,000 years

Explanation:

Radiocarbon dating (also referred to as carbon dating orcarbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Radiocarbon dating not good for material more than 30,000 years old because the amount of C14 becomes almost immeasurably small in 50,000 years
