Step 1: Check numpy addition methods
The+operator performs element-wise addition in numpy.Step 2: Evaluate options
a.add(b)is invalid because numpy arrays do not have anaddmethod.np.sum(a, b)computes sums, not element-wise addition.a.append(b)is a list method and errors on arrays.Final Answer:
a + b -> Option CQuick Check:
+operator adds arrays element-wise [OK]
Quick Trick: Use + for element-wise addition [OK]
