Show answer & explanation
Correct answer: C
Concept
In a blood-relation chain, decode each clue into a parent-child or spouse link first, then read the connection from the named person back to the target by following the chain of links. "Husband/wife" joins two people of the same generation; "daughter/son" moves down exactly one generation. The relationship two generations below a person (their child's child) is grandchild.
Tracing the chain
R is the husband of Q, so R and Q are a married couple in the same generation.
P is the daughter of R (and therefore of Q as well) — P is one generation below Q.
S is the husband of P, so S marries into P's generation; P is still one generation below Q.
E is the daughter of S and P — E is one generation below P, hence two generations below Q.
Result
E is the child of Q's daughter, i.e. two generations below Q and female. A female grandchild is a Grand Daughter, so E is the Grand Daughter of Q.
Cross-check
Count the downward steps from Q: Q → P (one step down) → E (a second step down). Two downward steps and E being female gives exactly "granddaughter", which confirms the result.
