Step 1: Interpreting the sentences.
The two given sentences state two negative facts: Ravi is not a technician, and Ravi is not a musician. We must combine them into one appropriate sentence.
Step 2: Evaluating the options.
(A) is grammatically incorrect and alters the intended meaning to positive.
(B) appropriately uses the correlative conjunction neither...nor to combine two negative statements into one proper sentence.
(C) alters the intended meaning by stating Ravi is a musician, which contradicts the original statement.
(D) also alters the intended meaning because it suggests Ravi is a technician.
Step 3: Final Conclusion.
Hence, the correct combined sentence is option (B), which preserves the original negative meaning properly.
