Assuming that numpy is imported as np$,$ what is a correct syntax to print the number $8$ from the array below:

arr $=$ np$.$array $([[1,2,3),[4,5,6],(7,8,9]])$

a$.$ print$($arr$[1,2])$

b$.$ print$($arr$[2,1])$

c$.$ print$($arr$(2,3])$

d$.$ print$($arr$[7,2])$

What is the output of the following code: import numpy as np

a $=$ np$.$array$($lio$,1,2],[3,4,51])$

b $=$ a$.$sum$($axis$=0)$

print $($b$)$

a$.3$

b$.12$

C$.[312]$ d$.[357)$

What would be the answer of this cummulative summation in NumPy?

arr $=$ np$.$array$([1,2,3])$

print$($np$.$cumsum$($arr$))$

a$.[9]$

b$.(369]$

c$.[136)$

d$.[6]$

What is the output of the following code: import numpy as np

x $=$ np$.$array$([4,-6,1,3,-7,0])$

print$($np$.$where$($x$>0,0,$x$))$

a$.[0-600-70]$

b$.(401300]$

c$.[413]$

d$.$ None of the above

In the given code, data frame $\text{'}$D$1\text{'}$ has

rOWS

and

$\_$ columns

import pandas as pd

df $=$ K$\text{'}$a$\text{'}$:$10,\text{'}$b$\text{'}$:$20),$ l$\text{'}$a$\text{'}$:$5,\text{'}$b$\text{'}$:$10,\text{'}$c$\text{'}$:$20),(\text{'}$a$\text{'}$:$7,\text{'}$d$\text{'}$:$10))$

D$1=$ pd$.$DataFrame$($df$)$

a$.3,5$

b$.3,4$

$.3,3$

d$.$ None of the above
