ANS:A - petrol.

'GASOHOL' widely used in Brazil as a motor fuel is a mixture of alcohol and petrol. Gasohol typically consists of a blend of gasoline (petrol) and ethanol (alcohol). In Brazil, ethanol is often derived from sugarcane and is commonly referred to as "ethanol" or "alcohol." Gasohol is used as a motor fuel in vehicles, providing an alternative to pure gasoline. The proportion of ethanol in gasohol blends can vary, but it is typically around 10% ethanol and 90% gasoline, although higher ethanol blends are also used, such as E85 (85% ethanol and 15% gasoline). So, the correct answer is: petrol.
