| Consider the following statements with regard to globigerina ooze, a type of ocean deposit. |

| 2. It is seldom found at a depth greater than 2000 fathoms because of their high solubility. |
| 3. It covers the largest area of ocean surface. |
| Which of the statements given above are correct? |
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) All of these
