Two long metallic strips are joined together by two rivets each of radius `2 mm`. Each rivet can withstand a maximum shearing stress of `1.5 xx 10^(9) N//m^(2)`. Assuming that each rivet shares the stretching load equally, the maximum tensile force the strip can exert without rupture is

A. `1.88xx10^(4)N`

B. `3.8xx10^(4)N`

C. `6xx10^(7)N`

D. `3xx10^(4)N`
