Five very long, straight insulated wires are closely bound together to form a small cable. Currents carried by the wires are: \[{{I}_{1}}=20\,A\], \[{{I}_{2}}=-6A\], \[{{I}_{3}}=12A\], \[{{I}_{4}}=-7A\], \[{{I}_{5}}=18A\]. (Negative currents are opposite in direction to the positive). The magnetic field induction at a distance of 10 cm from the cable is

• A. \[5\mu T\]
• B. \[15\mu T\]
• C. \[74\mu T\]
• D. \[128\mu T\]
