The correct option is A less than
When resistors are connected in parallel, the equivalent resistance is less than the lowest resistance in the circuit.
Proof is as follows:
As we know when R1, R2, R3 ... Rn resistors are connected in parallel circuit, the equivalent resistance of the circuit is
1Req=1R1+1R2...1Rn
1Req≥1Ri∀∈{1,2,3,....,n}
⟹Req≤Ri
