Ymorist [56]3 years ago
8 0

Answer:

Option C, The relative dating was done incorrectly.

Explanation:

As it is mentioned here in the description that scientist know that the actual age of rocks must be 2.5 billion years and this age of the rock must have been derived through some methodology of radioactive dating. Now since the potassium-argon method was used three times and it depicted the same result every time stating that the age of rocks is 1.3 billion years. Therefore there are high chances that earlier method used that estimated the age of rock as 2.5 billion years must be wrong.
