(A) the realization that as a person ages, their

(C) to realize that when a person ages, his or her

(A) the realization that as a person ages, their
(B) the realization that as people age, their
(C) to realize that when a person ages, his or her
(D) to realize that when people age, their - aging is a gradual process.
(E) realizing that as people age, their

imo- d...can someone explain why d is incorrect

I can point out following problems:
1. as vs when: aging is a gradual process. 'as people age, their concerns change as well' is correct. Eliminates C and D.
2. Subject-verb agreement. Eliminate A.

I am confused between B and E. Going for B because it sounds better to me, but I don't have any explanation for it.

IMO B.

Choices A and C can be eliminated very easily due to Pronoun Incongruity. A person...their does not make any sesnse.

For ruling out D the logic has been provided very aptly.

Between B and E, B is certainly a better choice. As E doesn't follow Parallelism. Realizing is a gerund, no other part of the non-underlined segment uses a gerund.

Going by the sounding logic, you many goof-up with the questions

oa is b...thank you all...good explanations

"The realization" is parallel to "Legacy",
"To realize" is NOT parallel to "Legacy";

Do not use "when" to describe prolonged process, use "as".

VodkaBoy,
Can you explain me how? I really don't know how they become parallel

VodkaBoy,

I think that they test here the following rule:
When you use "BE" to equate or compare two elements, the elements MUST be parallel:
- Vanilla IS more popular than chocolate;
- Seeing IS believing.

In our case:
- "One legacy ... IS the realization ... " - Good paralellism: noun=noun
- "One legacy ... IS to realize ... " - Bad paralellism noun is compared to infinitive.

I hope this will help
Good day!
