IKR Finance loaned $1,000 to Debtor. Debtor agreed to repay the $1,000 in one year, and one year, and Debtor signed a written security agreement granting IKR a security interest in an item of equipment owned by Debtor to secure this debt. IKR did not perfect the security interest. In this case:

	a.	The security interest is attached. If Debtor defaults, IKR can repossess and sell the collateral.
	b.	The security interest has not attached because IKR does not have possession of the collateral.
	c.	The security interest has not attached because IKR did not give value.
	d.	The security interest has not attached because IKR failed to perfect the security interest.
