Identify the error in this code snippet:
import numpy as np
from scipy.optimize import least_squares
def fun(x):
return x**2 - 4
res = least_squares(fun, x0=2, jac='3-point')
print(res.x)A'jac' parameter value '3-point' is invalid; should be '3-point' without quotes
B'jac' parameter value '3-point' is invalid; correct value is '3-point' (string) but spelled '3-point' is wrong
CThere is no error in the code snippet
D'jac' parameter value '3-point' is invalid; correct value is '3-point' with quotes
