A. Brassica campestris
B. Brassica oleracea
C. Both A and B
D. Capsella bursa pastoris

Answer 1

Mustard oil is made by grinding mustard seeds, mixing them with water, and then distilling the resulting volatile oil. The oil is produced by pressing the seeds or by grinding them, then mixing them with water and distilling them. The white mustard produces a yellowish brown, pungent oil, while the black mustard produces a lighter colored and better smelling oil.

Complete answer:
Option A: Mustard oil is made from the seeds of the mustard plant (Brassica campestris), which is a member of the cruciferous family. It is native to the Mediterranean countries, but it thrives in a wide range of climates. It has a distinctively pungent taste and scent. Though it has a nutty flavor, this oil is fine for the heart and has many other advantages. Mustard oil has anti-inflammatory effects due to its high selenium and magnesium content.
So, option A is correct.
Option B: The wild cabbage is Brassica oleracea. It does not contribute to the mustard oil.
So, option B is incorrect.
Option C: As, the mustard oil is obtained from Brassica campestris.
So, option C is incorrect.
Option D: The shepherd's purse is Capsella bursa pastoris. Capsella bursa pastoris , also known as shepherd's purse, is a small annual and ruderal flowering plant in the mustard family with triangular flat fruits that resemble purses.
So, option D is incorrect.

Hence, Option A. is the correct response.

Brassica is a plant genus that includes cabbage and mustard species. Informally, cruciferous onions, cabbages, and mustard plants are also members of the genus. Crops in this family are often referred to as Cole crops, which comes from the Latin caulis, which refers to a plant's stem or stalk. Mustard is a tall herb that can reach a height of a meter or more and has a pungent juice. The leaves are broad, lyrate, and alternate.
