Refer to the drawing of a simple chromel-alumel thermocouple circuit (see figure below).

Initially, the temperature instrument indicates 350°F.

A steam leak inside the reactor building (RB) increases the temperature of the thermocouple connection head, reference junction panel, and extension wires inside the RB from 120°F to 160°F.

The temperature at the location measured by the thermocouple remains the same.

What is the resulting temperature indication?

A. 310°F
B. 350°F
C. 390°F
D. 430°F
