I. C is shorter than F and E and D is taller than A and B.
II. E is shorter than B who is taller than A.

Options

A. If the question can be answered using one of the statements alone, but cannot be answered using the other statement alone.
B. If the question can be answered using either statements alone.
C. If the question cannot be answered even using A and B together.
D. If the question can be answered using A and B together but not using A or B alone.

Answer

C

Explanation

Using I alone,
`C lt F, C lt E`
`B lt D, A lt D`
So F, E or D can be tallest.
`therefore` I alone is not sufficient.
Using II alone
`E lt B`
`A lt B`
So B, or D can be the tallest.
`therefore` II alone is not sufficient.
Combing both also we cannot say who among them is the tallest.
