Directions: The following items consist of two statements, one labeled as “Assertion(A)” and the other labeled as “Reason(R)”. You are to examine the two statements carefully and decide if the Assertion(A) and the Reason(R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly.Assertion (A): For integrated circuit production the line width limit of optical Lithography lies near 0.4 μm, although 0.2 μm feature may eventually be printed under carefully controlled conditions.Reason (R): A negative resist on exposure to light becomes less soluble in a developer solution, while a positive resist becomes more soluble.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.
