Oleo gum resin (Asafoetida) can be obtained from:

dried latex from the tap root of ferula

 The correct answer is Option (4) -dried latex from the tap root of ferula

Asafoetida, a spice, is derived from the dried latex or gum oleoresin exuded by the underground rhizome or tap root of various Ferula species, perennial herbs reaching a height of 1 to 1.5 meters. Initially greyish-white, the substance darkens over time, transforming from yellow to red and ultimately brown.

Commercially available as blocks, pieces, or a fine yellow powder (occasionally crystalline or granulated), asafoetida's major components include resin (40-64%), gum (25%), and essential oil (10-17%). The distinctive aroma of asafoetida is primarily attributed to secondary butyl propenyl disulphide.
