Natalie Walter · Answer 1

c. int foo (char x);

Explanation:

Among the given options:

int foo (char x);

is a valid function declaration which declares a function with the name foo which takes a single character argument x and returns an integer data type.

Option a (void foo) does not specify the arguments off the function while option e (foo (int a, int b); ) does not specify the return type. Hence these are incomplete function declarations.
