Please identify the variables and the line number

Transcribed Image Text:question: Question 4
Consider the following Python program (note
that Python uses indentation to specify scope):
x = 1;
y = 3;
z = 5;
def subl():
010
020
030
040
050
a = 7;
y = 9;
z = 11;
# BODY OF SUB1
060
070
080
090
def sub2():
global x;
a = 13;
x = 15;
w = 17;
# BODY OF SUB2
def sub3() :
100
110
120
130
140
150
nonlocal a;
a = 19;
b = 21;
z = 23;
# BODY OF SUB3
160
170
180
190
200
Identify the variables that would be available
for assignment at BODY OF SUB2 (give the.
name and the line number where the name-
address binding is created).
Group of answer choices
x with binding created in 10
y with binding created in 20

a with binding created in 110
x with binding created in 120
w with binding created in 130
a with binding created in 160
a with binding created in 170
b with binding created in 180
