Step 1: Read both parts.
Assertion: GIFT is advised for a woman who cannot make ova but has a normal uterus. Reason: In GIFT a donor ovum is placed into the recipient's fallopian tube for fertilization inside the body.
Step 2: Recall what GIFT really is.
In GIFT (Gamete Intra Fallopian Transfer) an ovum from a donor along with sperm is transferred into the fallopian tube so that fertilization happens naturally inside (in vivo). It suits a woman who cannot provide a suitable environment in her own tubes but can still otherwise carry forward fertilization there.
Step 3: Test the Assertion.
The claim is that GIFT is for a woman who cannot produce ova. But GIFT uses an ovum (here from a donor) placed in the tube. The given assertion mixes up the situation and is not the correct description for that case, so the Assertion is false.
Step 4: Test the Reason.
The Reason correctly describes the GIFT method, a donor ovum transferred into the tube for in vivo fertilization. So the Reason is true.
Step 5: Combine.
We have a false Assertion but a true Reason.
Step 6: Conclusion.
Therefore the correct answer is "(A) is false. But (R) is true". \[ \boxed{\text{A false, R true}} \]
