Assertion (A): The triaxial body has survived as a formulation for centuries.
Reason (R): Its three components between them supply plasticity, fluxing and dimensional stability.

  • A.A is true but R is false
  • B.A is false but R is true
  • C.Both A and R are true, and R is the correct explanation of A
  • D.Both A and R are true, but R is not the correct explanation of A

Answer: C

Both are true and the reason gives the durability of the scheme: a body must be formable, must vitrify at an achievable temperature and must not distort, and these three materials answer all three requirements economically.
