if statement either says invalid syntax or unexpected indent, my first time using python (very simple code)

print ("Hey there Aga!")
print  (" ")
begin = input("would you like to begin?: ")
if begin == "yes":
print ("very well then, ill give you an easy question to find the password for the first folder..")
print (" ")
print ("A) Hajiko")
print ("B) Hajika")
print ("C) Hajima")
q1 = input ("what was the noise my phone made when we lost it?")
if q1 == 1
print ("yeah boy")

im so confused what do i do lmao, literally all that its saying is about the syntax or the indent??
