You can parse the JSON and iterate over the students array to print the email and each student's math score. In JavaScript:

```js
const data = {
  ename: "Sha",
  Section: "Yr1",
  Details: {
    contacts: {
      email: "jack@yahoo.com",
      Mobile: "123456789"
    }
  },
  students: [
    { id: "A3", Sname: "Jim", math: 60 },
    { id: "A4", Sname: "Dwight", math: 89 },
    { id: "A5", Sname: "Kevin", math: 79 }
  ]
};

console.log(`Email: ${data.Details.contacts.email}`);
console.log("Student marks:");
for (const s of data.students) {
  console.log(`${s.Sname}: ${s.math}`);
}
```

This prints the email followed by each student's name and math score. Complexity is O(n) where n is the number of students, as we traverse the array once.
