Predicting result of broadcasting

Binary arithmetic operations between two arrays are possible only when their shapes are compatible. Being compatible means either that the two arrays have identical .shape attributes or that their shapes satisfy certain rules. The rules for broadcasting in NumPy are summarized in the documentation.

Here, the NumPy arrays a, b, c, and d are provided for you. They differ in shape, number of dimensions, or in the extent of each dimension. Which of the possible sums listed below yields an array with shape (10,10)?
