1. Consider the following code given below ?

class Glove: 
    def __init__(self,color):
        self.__color = color 
    def get_color(self):
        return self.__color 
    def set_color(self,color):
        self.__color= color 
class Minion: 
    def __init__(self,glove): 
        self.__glove=glove 
        self.__color="Yellow"
    def get_glove(self):
        return self.__glove 
black_glove = Glove("Black")
red_glove = Glove("Red")
bob = Minion(black_glove)
black_glove.set_color(red_glove.get_color())
print(#line)

b. red_glove.get_color()
c. bob.get_glove().get_color()
d. bob.get_glove().__color

2. Consider the following code :

3. Find the output of the following code :

values = ["823", "863"]
num = values[0][0:]
for row in range(0,len(values)): 
    for column in range(0, len(values[row])):
        if num > values[row][column:]:
            num = values[row][column:]
print(num)

a. 2
b. 3
c. 23
d. 823

4. Consider the following code :

def function(string,list1):
    #line1
    while(num!=len(string)):
        if len(string)%2==0 or (string[num] in ('a','e','i','o','u')): 
            list1.append(string[num])
        #line2
        #line3
        break 
    return list1 
print(function("Epoch",[]))  

a. Line 1 : num=0, Line 2 : num+=1, Line 3 : function(string[num:],list1)
b. Line 1 : num=1, Line 2 : no code,Line 3 : list1 = function(string[num:],list1)
c. Line 1 : num=0, Line 2 : num+=1, Line 3 : list1 = function(string[num+1:],list1)
d. Line 1 : num=1, Line 2 : num+=1, Line 3 : list1 = function(string[num],list1)
