Afrom scipy.special import jn result = jn(3, 4.5)

Bfrom scipy.special import jv result = jv(4.5, 3)

Cimport scipy.special as sp result = sp.jn(4.5, 3)

Dfrom scipy.special import yn result = yn(3, 4.5)

Step-by-Step Solution

Solution:

Step 1: Identify the function for Bessel function of the first kind
The function jn(n, x) computes the Bessel function of the first kind of integer order n at x.
Step 2: Check the order and argument
Order is 3 and x is 4.5, so the call should be jn(3, 4.5).
Step 3: Verify import statement
Importing jn from scipy.special is correct.
Final Answer:
from scipy.special import jn result = jn(3, 4.5) -> Option A
Quick Check:
Order and argument positions are correct, and function matches the order type. [OK]

Quick Trick: Use jn(order, x) for integer order Bessel first kind [OK]
