The secretions of the bulbourethral glands empty into the spongy urethra.

Here's a step-by-step explanation:

1. The bulbourethral glands, also known as Cowper's glands, are two small glands located along the male reproductive tract.

2. These glands produce a clear, slippery fluid that is secreted into the urethra when a man is sexually aroused.

3. The fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.

4. The part of the urethra that the bulbourethral glands empty into is called the spongy urethra (also known as the penile urethra), which is the longest part of the urethra, and it travels through the length of the penis.

So, the correct answer to the multiple-choice question is "spongy urethra".
