Study the code below and determine which option represents the correct if$-$then$-$else statement for the given ternary operator:

Console.Write$("$What is the temperature today? $")$;

string input $=$ Console.ReadLine$()$;

double temp $=$ double.Parse$($input$)$;

string result $=($temp $>30)?"$It is hot today" : $"$It is not so hot today";

Console.WriteLine$($result$)$;

a$.$

$//$ Prompt the user to enter a temperature

Console.Write$("$What is the temperature today? $")$;

string input $=$ Console.ReadLine$()$;

double temp $=$ double.Parse$($input$)$;

string result $=$ string.Empty;

if $($temp $>30)$

$\{$

result $="$It is hot today";

$\}$

else

$\{$

result $="$It is not so hot today";

$\}$

Console.WriteLine$($result$)$;

b$.$

Console.Write$("$What is the temperature today? $")$;

string input $=$ Console.ReadLine$()$;

double temp $=$ double.Parse$($input$)$;

string result $=$ string.Empty;

if $($temp $>30)$

result $="$It is hot today";

if $($temp $<30)$

result $="$It is not so hot today";

Console.WriteLine$($result$)$;

c$.$

$//$ Prompt the user to enter a temperature

Console.Write$("$What is the temperature today? $")$;

string input $=$ Console.ReadLine$()$;

double temp $=$ double.Parse$($input$)$;

string result $=$ string.Empty;

if $($temp $>30)$

result $="$It is hot today";

if $($temp $=<30)$

result $="$It is not so hot today";

Console.WriteLine$($result$)$;

d$.$

$//$ Prompt the user to enter a temperature

Console.Write$("$What is the temperature today? $")$;

string input $=$ Console.ReadLine$()$;

double temp $=$ double.Parse$($input$)$;

if $($temp $>30)$

string result $="$It is hot today";

if $($temp $<=30)$

string result $="$It is not so hot today";

Console.WriteLine$($result$)$;
