Which of the following code fragments contain obvious semantic errors?

A$.x=1+1$

B$.x={\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(input())$

$y=x+2$

print$(\text{'}$The sum of the inputted number and $2$ is $\text{'}+str(x))$

C$.$ import math

$x=9$

math.sqrt $($x$)$

print$(\text{'}$The square root of $9$ is $\text{'}+str(x))$

D$.$

E$.$ total $=3+5**20$

print$(\text{'}$The total is computed by adding $3$ and $5$ and then multiplying by $20,$ which gives us $\text{'}+$ str$($total$))$

F$.$ print plus $\text{'}+2+\text{'}$ is $($:${?}^{\text{'}}+4\}$
