Consider the system of linear equations\( x + y + z = 4\mu, \quad x + 2y + 2\lambda z = 10\mu, \quad x + 3y + 4\lambda^{2} z = \mu^{2} + 15 \), where, \( \lambda, \mu \in \mathbb{R} \). Which one of the following statements is NOT correct?
The system has infinite number of solutions if \( \lambda = \dfrac{1}{2} \) and \( \mu = 15 \)
The system is inconsistent if \( \lambda = \dfrac{1}{2} \) and \( \mu \ne 1 \)
The system is consistent if \( \lambda \ne \dfrac{1}{2} \)
The system has unique solution if \( \lambda \ne \dfrac{1}{2} \) and \( \mu \ne 1, 15 \)
