Let $J_{n, m}=\int_{0}^{\frac{1}{2}} \frac{x^{n}}{x^{m}-1} d x, \quad \forall n>m$ and $n, m \in N$. Consider a matrix $A=\left[a_{i j}\right]_{3 \times 3}$ where $a_{i j}=J_{6+i, 3}-J_{i+3,3}$ for $i \leq j$ and $a_{i j}=0$ for $i>j$. Then $\left|\operatorname{adj} A^{-1}\right|$ is:

  • A
    $(15)^{2} \times 2^{42}$
  • B
    $(15)^{2} \times 2^{34}$
  • C
    $(105)^{2} \times 2^{38}$
  • D
    $(105)^{2} \times 2^{36}$
