Boolean age group question: Why is this invalid syntax?

Question

Im trying to do the Boolean age group challenge and it keeps saying line #9 is invalid syntax. What have I done wrong?

age = int(input())
# your code goes here

if age>0 and age<=11:

print("Child")

elif(age>=12 and age<=17):

print("Teens")

elif(age>=18 and age<=64):

print("Adult")

elif(age>64):

print("Senior")

Answer 1

If and elif statements have to be aligned vertically.

if condition:
print()
elif condition:
print()

Answer 2

age = int(input())
# your code goes here

if age>0 and age<=11:

print("Child")
elif(age>=12 and age<=17):

print("Teens")

elif(age>=18 and age<=64):

print("Adult")

elif(age>64):

print("Senior")

Answer 3

It is an indentation error

Answer 4

This also works perfectly:
age = int(input())
# your code goes here

if age>=0 and age<=11:
print("Child")
if age>=12 and age<=17:
print("Teen")
if age>=18 and age<=64:
print("Adult")
if age>=65:
print("Senior")
