Resistivity of copper, nichrome and a semiconductor varies with temperature respectively as

Linear, exponential increase and exponential decrease Exponential increase, linear and exponential decrease Exponential increase, exponential decrease and linear Linear, exponential decrease and exponential increase

Exponential increase, linear and exponential decrease

The correct answer is option (2) : Exponential increase, linear and exponential decrease For Copper $\to$ exponential increase For Nichrome $\to $ linear increase For Semiconductor $\to $ exponential decrease
