An analyst created a map and shared it with the organization. The map references

c. Two cosigners needed.

Explanation:

In the first if condition,

if ($age >= 21 && $score >= 700)

The age variable is set to 19, which is not >=21, so this condition is false.

In the second condition,

else if ($age >= 21 && $score >= 650)

Same story, age variable is equal to 19, which is not >=21, this condition is also false.

In the third condition,

else if ($age >= 18 && $score >= 680)

age condition is true because 19 is >=18, and score condition is also true, because 750 is >=680. So this condition is true.

Henceforth, variable message will contain the string "Two cosigners needed."
