Final answer:
The question seems to mix food preparation steps with a term that could refer to a biological pesticide. In biological contexts, Mango BT would likely relate to Bacillus thuringiensis, which would have a very different SOP involving safe dilution and application as a pesticide.
Step-by-step explanation:
It seems like there might be some confusion in the question. The Standard Operating Procedure (SOP) mentioned in the question seems to pertain to the preparation of a drink or food product, which would generally not fall under Biology. However, if we are discussing Regular Mango BT, and BT stands for Bacillus thuringiensis, which is a commonly used biological pesticide in agricultural practices, the SOP would be quite different and not related to the options provided (mixing with water, brewing, adding sugar, or roasting). In that case, the SOP would be specific to the product label and might involve steps like dilution in water at recommended rates, application via spraying on crops, and adhering to safety guidelines for handling biological pesticides.
