Metallic bond is a bond between two metal atoms. Here in the given option Hg is the only metal with metallic bond.

Fat is completely digested in the small intestine of the body.

From the given circuit,

The resistors R1 and R2 are in parallel connection and R3 is in series with R1 & R2

The equivalent resistance of R1 and R2 is

Req = (12 × 4)/(12 + 4) = 3 Ω.

Adding R3 in series with the pair gives

R = Req + 9

R = 3 + 9

R = 12 Ω.
