Which of the following is the correct syntax to save an array of numerical data, arr to a .txt file, output.txt, separated by commas, rounded to 4 decimal places, with the column headers col1, col2, and col3?

np.savetxt("output.txt", arr, delimiter=",", fmt="%.4f", comments = "")

np.savetxt("output.txt", arr, delimiter=",", comments = "")

np.savetxt("output.txt", arr, delimiter=",", fmt="%.4f", header="col1,col2,col3", comments = "")

✅

np.savetxt("output.txt", arr, delimiter="\t", fmt="%.4f", header="col1\tcol2\tcol3", comments = "")

np.savetxt("output.txt", arr, delimiter="\t", fmt="%.4f", header="col1,col2,col3", comments = "")

np.savetxt("output.txt", arr, comments = "")

np.savetxt("output.txt", arr, delimiter=",", fmt="%.4f", header="col1\tcol2\tcol3", comments = "")
