On executing the following commands, Broadcasting in numpy will produce

निम्नलिखित आदेशों को क्रियान्वित करने पर, numpy में प्रसारण का उत्पादन होगा

a = np.array((0,10,20,30))
b = np.array((0,1,2)) 
y = a[:, None] + b

Error, operands could not be broadcast together with these shapes

[[ 0 10 20, 30] [10 21, 32] [20 31 22] [30 31 32]]

[[ 0 0 0] [0 0 0] [0 0 0] [0 0 0]]

[[ 0 1 2] [10 11 12] [20 21 22] [30 31 32]]

Explanation:

The operation a[:, None] + b adds b (shape (3,)) to each element of a (shape (4,)) by broadcasting. This creates a (4, 3) array:

[[ 0  1  2]
 [10 11 12]
 [20 21 22]
 [30 31 32]]

So, the correct answer is (D).
