**Core Concept**
Today contraceptive is a type of emergency contraceptive pill (ECP) that is designed to prevent pregnancy after unprotected sex or when a regular contraceptive fails. It contains a combination of two hormones, ulipristal acetate and ethinyl estradiol, which work to prevent ovulation and fertilization.

**Why the Correct Answer is Right**
Ulipristal acetate is a selective progesterone receptor modulator (SPRM) that inhibits the action of progesterone, leading to the suppression of ovulation and the prevention of fertilization. Ethinyl estradiol is a synthetic estrogen that helps to regulate the menstrual cycle and prevent ovulation. The combination of these two hormones in Today contraceptive makes it an effective ECP.

**Why Each Wrong Option is Incorrect**
**Option A:** The Today contraceptive does not contain levonorgestrel, which is a different type of progestin used in other emergency contraceptive pills.
**Option B:** The Today contraceptive is not a copper intrauterine device (IUD), which is a different type of emergency contraceptive method.
**Option C:** The Today contraceptive does not contain medroxyprogesterone acetate, which is a type of progestin used in injectable contraceptives.

**Clinical Pearl / High-Yield Fact**
It's essential to note that Today contraceptive should be taken as soon as possible after unprotected sex, ideally within 120 hours (5 days) for optimal effectiveness. This highlights the importance of timely intervention in preventing pregnancy after emergency situations.
