A combination of two resisters R(1) and ...

A combination of two resisters `R_(1)` and `R_(4)` are placed in an electrical circuit. In an experimental arrangement, the resistance are measured as `R_(1)=(100 pm 3)Omega , R_(2)=(200 pm 4)Omega`
The equivalent resistance, when they are connected in parallel, `(1)/(R_(P))=(1)/(R_(1))+(1)/(R_(2))` can be expressed as

A

`(66.7 pm 12)Omega`

B

`(66.7 pm 7)Omega`

C

`(66.7 pm 4.9)Omega`

D

`(6.7 pm 1.8)Omega`
