In the generation of element geometries, if dx dy represents an area element in the real element and dεdη represents the corresponding area element in the master element, then what is the expression for Jacobian je?a) (dx dy) (dεdη)b) \(\frac{dx}{d\epsilon} \frac{dy}{d\eta}\) c) \(\frac{d\epsilon}{dx} \frac{d\eta}{dy}\) d) \(\frac{1}{(dx dy) (d\epsilon d\et

• A. (dx dy) (dεdη)
• B. \(\frac{dx}{d\epsilon} \frac{dy}{d\eta}\)
• C. \(\frac{d\epsilon}{dx} \frac{d\eta}{dy}\)
• D. \(\frac{1}{(dx dy) (d\epsilon d\eta)}\)
