Question

Arrange the below doses in a sequence that cause low to high percent deaths in a population:
(A) LD99
(B) LD25
(C) LD1
(D) LD50
Choose the correct answer from the options given below:

• A. (A), (D), (B), (C).
• B. (C), (A), (B), (D).
• C. (C), (B), (D), (A).
• D. (C), (D), (A), (B).

Hint:

The subscript number in "LD" directly tells you the percentage of deaths. Simply arrange the numbers in ascending order: $1% < 25% < 50% < 99%$, which gives the sequence C $\rightarrow$ B $\rightarrow$ D $\rightarrow$ A.
