You have been given an assertion statement and a reason. Select from A- D to locate the correct statement ? A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true. Assertion (A): AgBr will precipitate before AgCl when a solution containing 0.050 M AgNO₃, 0.030 M NaCl, and 0.030 M NaBr is mixed. Reason (R): Ag⁺ ions have a stronger attraction to Br⁻ than to Cl⁻ because bromide is a larger anion.
