At room temperature `(27.0°C)` the resistance of a heating element is `100 Omega`. What is the temperature of the element, if the resistance is found to be `117 Omega`, given that the temperature coefficient of the material of the resistor is `1.70 xx 10^(-4)`/°C.
Options:
(a) `27°C`
(b) `1027°C`
(c) `17°C`
(d) `117°C`
