5. c

Explanation:

R1 and R2 show parallel combination. Sly, R3, R4, R5 also show parallel combn. But these two combinations together create a series combn. Series combn gets u resistances added by summation of resistances (and not unverse of resistances), hence, max resistance is provided. For eg. take 2 resistances of 1ohm each, series will give uh 2ohm of equivalent resistance and 1/2 ohm of Req in parallel, so u can see that series combn gives max resistance. It's the resistance which depends on dimensions and resistivity of material. But resistivity will only depends on nature of material. Lastly, rheostat is a device which measures resistance. ammeter measures current, and voltmeter measure volatage.

Hence ans's provided.

Hope it helped!
