In an objective paper, there are two sections of 10 questions each. For "section 1" , ech question has 5 options and only one option is correct and "sectin 2" has 4 option with multiple answer an marks for a question in this section is awarded only if he ticks all correct answers. Marks for each question in "section 1" is 1 and in "section 2" is 3. (therefore is no negativve marking.)
If a candidate attempts only two questions by guessing, one from "section 1" and one from "section 2", the probability that he score in both questions is

A

`(1)/(15) ((1)/(15))^(2)`

B

`(4)/(5) ((1)/(15))^(3)`

C

`(1)/(5) ((14)/(15))^(3)`

D

none of these
