A carbon and an aluminium wire are connected in series . If the combination has equivalent resistance of `90 Omega` at 0°C, the value of the resistance of each wire at 0°C so that the resistance of combination does not change with temperature is (`alpha_c=-0.5×10^(-3)°C^(-1)` and `alpha_Al=-4×10^(-3)°C^(-1)`)

Options

A. `R_(0,c)=80/9Omega` , `R_(0,Al)=10/9Omega`
B. `R_(0,c)=80Omega` , `R_(0,Al)=10Omega`
C. `R_(0,c)=730/9Omega` , `R_(0,Al)=80/9Omega`
D. `R_(0,c)=10Omega` , `R_(0,Al)=80Omega`
