    Answer : Option A

    Explanation :

    >> char str1[20] = "Hello", str2[20] = " World"; The variable str1 and str2 is declared as an array of characters and initialized with value "Hello" and " World" respectively.

    >> printf("%sn", strcpy(str2, strcat(str1, str2)));

    => strcat(str1, str2) it append the string str2 to str1. The result will be stored in str1. Therefore str1 contains "Hello World".

    => strcpy(str2, "Hello World") it copies the "Hello World" to the variable str2.

    Hence it prints "Hello World".
