Asphixiation is a hazard posed by compressed natural gas (CNG) vehicles and can be detected when you notice this smell a) Rotten Eggs
b)Cinnamon
c)Burning
d)spoiled milk

The correct option is;

a) Rotten eggs

Explanation:

Asphyxiation hazard posed by compressed natural gas (CNG) can be detected when the smell of rotten eggs is noticed

Compressed natural gas is made 90% of the colorless and odorless gas, but highly combustible gas, methane, a gaseous additive known as Mercaptan that has the smell of rotten eggs is added so that a person can become alerted by the smell given off in the system should there be a leak.

The smell of the Mercaptan can be detected as low as when the concentration of the the CNG is 1/16 times the concentration required for the combustion of the CNG.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
