The question asks what is NOT an exception to 'No Consideration, No Contract'. The valid exceptions under Section 25 of Indian Contract Act are: natural love and affection (B), promise to compensate for past voluntary services (not involuntary), agency contracts (C), and gifts (D). Option A - 'Compensation for involuntary services' - is NOT an exception. The valid exception is compensation for VOLUNTARY services, not involuntary ones. The question tests precise knowledge of this distinction.
