A company wants to start making use of AWS Machine learning. The main aspect of the program would be to determine if the reviews written on their web site was done by a customer or a bot. Which of the following classifications in ML would you make use of?

Answer options:

A.Single class
B.Multiclass
C.Binary
D.Regression

Answer - C
The AWS Documentation mentions the following
You can use supervised ML approaches for these specific machine learning tasks: binary classification (predicting one of two possible outcomes), multiclass classification (predicting one of more than two outcomes) and regression (predicting a numeric value).
Examples of binary classification problems:
Will the customer buy this product or not buy this product?
Is this email spam or not spam?
Is this product a book or a farm animal?
Is this review written by a customer or a robot?
