There is an inverse relation between the tin in the tin-lead ratio and the melting point of the soldier, this means that as the amount of tin increases in the tin-lead ratio, the melting point decreases and vice versa.
Based on this, the soldier with the lowest melting point is the one with the highest tin ratio.
Answer : (B) 70/30
