Consider the following statements regarding metamorphic rocks:<br>1. Ortho-metamorphic rocks are formed from igneous rocks.<br>2. Intense heat of the intruding magmas results in metamorphism of the surrounding rocks, a process known as dynamic metamorphism.<br>Which of the statements given above is/are <strong>CORRECT</strong>?

  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2

Correct Answer: A. 1 only

Explanation

Statement 1 is correct; ortho-metamorphic rocks derive from igneous rocks (while para-metamorphic derive from sedimentary). Statement 2 is incorrect because metamorphism driven by the intense heat of intruding magma is called contact (or thermal) metamorphism, not dynamic metamorphism.
