(A) 50,000 to100,000 of the different genes found in a human cell are contained in merely

"information encoded in .... different genes" - is the correct expression and not "information encoded in ... of different genes"

Therefore now we can shortlist Option C and E
Also, information is the singular subject therefore, "found in a human cell is contained" will be the correct subject verb agreement
thus, answer is "E"

The usage of the definite article ‘the’ is one key to the right answer. The text means to say that the each human cell contains in all some 50,000 to 100,000 genes. (That is all, no more). This entirety is brought out by the use of the definite article. Choices which do not use ‘the’ mean that only
50,000 to 100,000 thousand genes of possibly a higher number than that are contained in a cell.
This critical difference leaves us only with choices C and E.
Information is a singular noun and therefore ‘is contained’ is the suitable verb. E is the choice.

Simple POE:

1. all of the information (singular), hence is/are - 'is' reqd here

Eliminate A,B,C

2. A definite article 'the' is reqd here to say that the each human cell contains in all some 50,000 to 100,000 genes.

hence, E
