Vessels in parallel, calculate the resistance

A set of vessels are arranged in parallel. Resistance in each of the four vessels is 2mmHg/mL/min (R1=R2=R3=R4=2mmHg/mL/min). What is the total peripheral resistance of the circuit?

1) 16 mmHg/mL/min
2) 8 mmHg/mL/min
3) 4 mmHg/mL/min
4) 2 mmHg/mL/min
5) 1 mmHg/mL/min
6) 0.5 mmHg/mL/min
