Concat 2 arrays horizontally,
a = np.arange(1,17).reshape(4,4)
b = np.arange(17,33).reshape(4,4)
np.hstack((a,b))
np.concatenate((a,b), axis = 0)
A, B and C are correct option
np.concatenate((a,b), axis = 1)
Both A and B
how can be the answer is both a and b its wrong
Hey @Nikhil799, you are right, the answer to this question is wrong. It is not Both A and B . The correct answer should be 1st and 4th Option. I have informed our backend team and they will update the quiz soon. Thank you so much for pointing this out to us 
Hope this clears your doubt !
