Which of the following expressions indicates $\text{‘R’}$ is the sister of $\text{‘H’}$ ?

• A. $\text{H \$ D @ F # R}$
• B. $\text{R % D @ F \$ H}$
• C. $\text{R \$ D @ F # H}$
• D. None of these

Answer 1

Option (B) is correct.

• $R\%D:$ R is the daughter of D.
• $D@F:$D is the husband of D, and R is the child of D, F.
• $F\$H:$F is the mother of H.

D and F are couples here who have 2 children (R, H) since R is female and H's gender is not clear.so R is the sister of H.
