Question

Assertion (A) : The milk produced by transgenic cow 'Rosie' was nutritionally more balanced product for human babies than natural cow milk.
Reason (R) : It was human protein enriched milk containing human alpha lactaglobulin.

• 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 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.

Hint:

Rosie milk contained human alpha-lactalbumin, not alpha lactaglobulin, so R is false while A is true.

Answer 1

The Correct Option is C

Step 1: Check the Assertion
Rosie, the first transgenic cow (1997), gave milk that was richer in a human protein and more balanced for human babies than ordinary cow milk. So (A) is true.

Step 2: Check the Reason
The human protein in Rosie milk was alpha-lactalbumin (about 2.4 g per litre). The reason names alpha lactaglobulin, which is not the protein concerned. So (R) is false as printed.

Step 3: Choose the option
A is true and R is false, which is option (C) and matches the official key.

Final Answer:
Option (C): Assertion (A) is true, but Reason (R) is false.
