Which code example is an infinite loop?

Group of answer choices

loopNum $=1$

while loopNum$<=5$:

print$($loopNum$)$

loopNum $+=1$

loopNum $=1$

while loopNum$<=5$:

print$($loopNum$)$

for loopNum in range$(0,5)$:

print$($loopNum$)$

loopNum $=1$

while loopNum$<=5$:

print$($loopNum$)$

loopNum $=$ loopNum $+1$
