Correct Answer: 87762510

Solution : Given:
TEACHER is written as 2513859, and PRESS is written as 7951010.

In two–digit positional value determine the sum of the digits and write the positional value of one digit of TEACHER, to obtain the code –
T→20 = 2 + 0 = 2; E→5; A→1; C→3; H→8, E→5; R→18 = 1 + 8 = 9
Thus, TEACHER is coded as 2513859.
And in, PRESS is written as 7951010 –
P→16 = 1 + 6 = 7; R→18 = 1 + 8 = 9; E→5; S→19 = 1 + 9 = 10; S→19 = 1 + 9 = 10
Thus, PRESS is coded as 7951010.
Similarly, by following the same pattern for ZYGOTES, the code is as follows –
Z→26 = 2 + 6 = 8; Y→25 = 2 + 5 = 7; G→7, O→15 = 1 + 5 = 6; T→20 = 2 + 0 = 2; E→5; S→19 = 1 + 9 = 10

Thus, ZYGOTES is coded as 87762510. Hence, the fourth option is correct.
